Antec cases made a good impression on me. Antec’s P280 reminded me of the good times I had worked with Corsair 600T.

Now the reason I am saying is that Corsair 600T– for a mid tower case- is insanely roomy- almost enough to comfortably convince you can mount an E-ATX form factor. That’s how mid-tower cases that cost more than Rs. 5,000/- or USD 90 should be! If not, then the case should have enough features to make up for it!

Antec Eleven Hundred is a mid-tower case, but looking at the paper specs it almost qualifies as a super mid-tower. Still, whether it is or not a super mid-tower, what matters is if this case is good enough to shortlist- and if it is, just how good is it?

Edit: Antec DID mention this as a super mid tower in their PDF copy of the manual and on online retails sites, but not on their specifications page.

Antec’s packaging is similar to how it was with P280. All the explanation about the specification and features are on the top and rear side of the packaging.




Just like P280, Antec uses Polyethylene Foam and not Styrofoam- a material more suitable to protect such cases. My opinion about such packaging material is already mentioned here. There’s a thin sheet of cardboard to protect the front panel.


P280 is 526mm in height, 231mm by Width and 562mm in depth, whereas Eleven Hundred is 527 mm in height, 237 mm in width, but shorter in depth with 546 mm. The net weight is also lesser compared to P280. P280 had a front door with 2x 120mm Antec fans on the front and 1x 120mm Antec fans on the rear with TwoCool controls, but in Eleven Hundred, You’re getting a 200mm fan on the top and a 120mm fan on the rear. You don’t have 2x 120mm mount on the top panel so this case is more for those who are into air-cooling or just with a single 120mm closed loop AIO CPU Liquid Cooler.

But they have the same drive bay counts- both 3.5” and 5.25” drives and they have 2x USB 3.0 and 2x USB 2.0 connector with the usual audio connectors and power/reset button. Both cases can accommodate 13” long graphics cards… the list goes on.

The case is made of steel with matte black finish and a plastic front panel.


The left sidepanel has a transparent window with 2x 120mm mount. The right panel has a protruding design with a 120mm mount to cool that particular area where the processor is mounted towards the left. Antec should have at least used the same protruding design on the left sidepanel as it did on the right sidepanel.

The mesh does not come with filters.


The front panel has a mesh for the 2x 120mm on the front and for the 5.25” bay. There are some designs on the side. The rear panel has the same vents on the right sidepanel section as P280 did. Fan controller hub on the top with a 120mm fan for the rear exhaust, 9x reusable vented PCI slots and vented area with rubber grommets on the side to reroute water cooling tubings and the usual area for mounting power supply on the bottom.

Talking about the front panel connectors,


From Left: Pinhole size HDD Activity LED, 2x audio connectors (headphone and mice), 2x USB 2.0 and 2x USB 3.0 ports followed by another pinhole size LED indicator for power.


The top panel is where you access the Power and Reset buttons. There’s the 200mm fan which pushes the air out.


On the underbelly of the case is where it has the mesh for the PSU’s fans and 4x case feet secured with plastic push pins to secure them.


The case feet are plastic. P280 had a white silicone base but then P280 was designed to dampen noise and vibration. Regardless, plastic push pins are something I don’t really prefer. In situations with a fully loaded rig in such case and if you’re moving it a bit while without lifting the case and if the standoff breaks- whoops! I would prefer if the metal screw was secured against the case- with a small nut secured from the inside to hold it in its place- something like many case manufacturers do- and something that you get in aftermarket modding retail stores.


The sliding air filter for the power supply is on the base, but the frame can be pulled out from the sidepanel section and unlike most cases where you pull it from the rear panel.


The framework is no different from P280- with an exception that P280 uses tray mounts for storage drives, and Eleven Hundred uses HDD slides.

There are 4x rubber grommets for cable routing and 2x routing holes on the top of the motherboard tray.


Nothing new from the rear panel view from the inside- except that the plastic grip for removing PCIe vents. The front panel also has internal mounting clips for 2x 120mm fans just like P280 did.

Just as an example, this is how easy the fan mount is:


Even fans with thick silicone corners such as Antec’s TrueQuiet and Corsair’s AF Series fans have isn’t a problem to mount them with ease.


As one can guess it from the underbelly view on the previous page, the base doesn’t have a 120mm fan mount. Then again, too many fan mesh means a requirement of more filters, but it makes a lot more sense than having a fan mount for the right sidepanel for a lot of end users.

The top panel is where the large 200mm fan is and its mount to push the air out. Looking at the advertised specs, there’s no 2x 120mm fan provided on the front. That’s disappointing. When you’re buying a case- with exceptions of $50 or underpriced cases- you will expect bare essentials- fans on the front and rear. So you end up buying 2 more fans of your preference to mount them on the front panel. But why would Antec do that- and not have a top panel mount for 240mm radiators???

The case’s structure is as same as Antec P280 so if you’ve read that, the pros and cons are going to be similar.


The 5.25” bay mounting is how most cases have- from the left sidepanel view there are the tool-less clips, and from the right panel it clips to hold the drive in place.


Let’s cut it short and simple. It’s basically a P280 with many differences. You get the same stuff with certain obvious differences out of which most of them didn’t make sense at all.

One of them is this:


The grommets are glued to the tray’s mounting cut-out- and not like P280 where the grommets are clipped on the motherboard plate itself. Eleven hundred is the cheaper P280, but I wonder how much is Antec saving from letting the grommets be clipped on the case and not glued.


The right-angled routing hole with cable tie clips just like the P280.


Since it’s the same body as P280- same generous space for routing the thickest of cables- especially the 24- pin motherboard power cable.


The cases use USB 3.0 header and the 1x USB 2.0 header. I am guessing that HD Audio cable will be as short as P280.


Antec’s 4 pin Molex hub powers up 4 fans via 3/4pin connectors. The plastic frame that clips on Antec’s fan controllers are bit different. The one of the left is made as if it holds a single frame with 2 controllers unlike the one in the right.

And that’s the case.


The 200mm fan comes with that mounting but with only a single controller. Why not just have a single plastic frame in that case?


The rear 120mm fan comes with a ridiculously short (12 cm) header. no extension- no pin to Molex adapter. It is not long enough to connect the motherboard’s 3/4 pin fan connector viz. usually either near Northbridge/PCIe slot side. So- you HAVE to route a 4 pin Molex connector all the way up just to power up the rear fan.

I am disappointed at this point as well:



The 2x 120mm front panel’s air filter is not installed on the body. Rather its installed on the front panel frame. So obviously there will be some space between the frame and the body (wasn’t that the point of having the filter on the body and not on the frame unless it’s a removable type like 500R?) On top of it, there are these opening to let the air in and they don’t have filters on it.


Towards the side of 5.25” bay on the sidepanel, you can see the routing holes for routing 120mm fans’ wires. Thanks to ample space that both P280 and Eleven Hundred has, the plastic connector of Molex will not be an obstacle when securing the right sidepanel after setting the system.

You can see the hinge support for P280’s fan filter on the right of the front panel. Rest is the same as P280, including the plastic casing for the front panel. You can mount 2x 120mm fans, but unlike P280 which had 2x 120mm fans on the top which could have been removed and installed here, you end up buying them.



The accessory box comes with 12 slides for 6x 3.5” HDD devices and the required screws and instruction manuals.

In all honesty, what Antec could do is at the very least provide a screw+ nut add-on as an alternate for plastic standoff for the case feet, but it’s more likely to see that being used by default rather than providing extras.

It gives me great pleasure that companies such as Antec, Asus, Gigabyte, Noctua, Kingston, Western Digital and Coolermaster who give me hardware support by updating my test rig no strings attached. It’s because of these guys that I get to test only their hardware but also from others. Thumbs up to these guys!

The only part that you’re losing out on slides is that you won’t get to mount 2.5” SSD/HDD devices like how one can do on the P280. You can slide in a couple of SSD on the HDD bay but…

IMG_0699 IMG_0734 IMG_0703

You can see that the 2x SSD drives mounted on top of 6 stacks of HDD drives, it’s awfully close. The part of the SSD from the left sidepanel sticks out whereas from the right sidepanel you’ll need to reach in to connect the SATA power and SATA cables. It’s frustrating, especially if you end up in a situation where you use a SATA power connector on the middle of the cable when you install 2 SSD drives at the same time.

Also, I ended up taking out the drive, connecting the non-right-angled SATA cable and SATA Power to Molex cable if I use 2 SSDs at the same time. The SSD slots need more space between them and the first HDD slot. This wasn’t really an issue with P280 because the tray mount that you get with it has a 2.5” installation holes.

But when it comes to mechanical drives an irrespective of the thickness, there’s ample space between them.


Just like P280, installing the brass standoff is a bit difficult at first, which thankfully I have a standoff wrench to solve the problem. But for those who don’t?


Antec needs to be generous in wire/cable length. While it may not be a problem with motherboards with Audio header on the corner right section of the layout, it is going to be an issue with either mATX, ATX and also with sound cards. They also should an inch or 2 longer front panel header.

Remember Storm Trooper? You get an 8 pin EPS extension cable should your cable from the power supply cannot reach. That’s standard add-on that all cases should have if they come with a 9 slot E-ATX layout. I bumped in a scenario with P280 where the fitting of this cable is tight, but with Antec Eleven Hundred, I wasn’t able to do so.


Why did it happen over here and not with P280? Maybe because I routed the cable for Asus GTX 660 on this case and not on P280? Nah.

But I did stretch the cable as much as I can on P280, something I am not comfortable with- and something I am not comfortable when doing the same over here too. Extension cable the 4/8 pin ATX/EPS cable should come with larger than ATX cases.


On most count, it is not going to be an issue with the Fan connector hub.



Thanks to the extra space between the HDD/5.25” bar and the motherboard, there’s a lot of areas which aids in having cleaner cable management even if you’re trying to put a system up quickly, but I ended up routing the EPS cable from the left sidepanel section. If you have a card as long as 10:5” and your motherboard layout allows you to install a PCI x1 card below it, you could hardly make out if there’s a cable running through. It will be noticeable if I connect the front panel audio panel header in the same way- just like how I did in P280.

Longer wire leads and cables!!!


I am not sure why Antec doesn’t call these cases as E-ATX compatible. Few PC builders have already confirmed that they were able to easily fit Asus ROG motherboards with EATX form factor with no obstacles whatsoever. It makes more sense. The difference between putting ATX/m-ATX form factor boards is negligible- except you lose out on some PCI slots and the layout may be cramped if the manufacturer is putting a lot of things and the manufacturer didn’t plan the layout properly.

When I powered up and used the case for a while, the top mount fan makes an audible sound. It’s not annoying at first, but I wouldn’t be surprised if it increases as it gets older and older. I think it is because these are sleeve bearing. Sleeve bearing fans are best avoided for a horizontal mount.

It’s extremely annoying. Just how many 200mm non-sleeve bearing fans do you get in the market? Some may end up disconnecting it and AGAIN- since you can’t re-use it mount a 120/ 140mm fans on top, the top fan section is wasted.

Here’s the problem:

  • There’s no 2x 120mm fan mount. Rather you have a 1x 200mm fan (possibly sleeve bearing) mounted horizontally on the top panel. Providing 2x 120mm fans is more useful than a single 200mm fan. You don’t get many 200mm non-sleeve bearing fans compared to 120mm counterparts, let alone 140mm.
  • The sound from the 200mm fan in full speed is audible.
  • There’s no 2x 120mm fan on the front.
  • The front panel air filter should have been on the case rather than on the front panel frame.
  • Annoying experience when installing 2x 2.5” SSDs at the same time.
  • No filters on the left and right sidepanel.
  • Plastic pushpins for the case feet.
  • Should provide EPS extension cable.
  • Most header and front panels connector cables need to be longer.
  • The grommets are glued.

Let’s be realistic, this case is made to be cheaper than P280 obviously. But how cheap is it?

The prices for P280 are as follows:

India U.S. U.K.
Rs. 9,558/- $115.09 £89.99

Do note that these prices are via Flipkart which is currently pricing a lot of good more price than what they cost, but Antec P280 costs Rs. 8,500/- INR in PC H/W Retail stores.

And for Eleven Hundred:

India U.S. U.K.
Rs. 8,862/- $119.99 £90.22

Summary : Throw in few notes and buy P280, you’re doing lot more justice for your money. You get the tray mounts which will let you install 2.5” drives wherever you want. Let’s not forget the silicone mount for 3.5” drives on those trays to absorb vibration? You get a mount of 2x 120mm fan on the top with pre-installed fans and you can route them and mount them on the front. The grommets are clipped so they’re going to stay in their place. You don’t need to open the front panel to remove the filter that is on the panel and not on the chassis- all you end up doing is open the door and remove the front panel air filter. Simple!!! On top of it, there’s an extra layer on the sidepanels to dampen any noise and the case feet on P280 has a soft silicone base.

Keeping this in mind and since the framework on Eleven Hundred is as same as P280 with some minor cash difference but a lot more offerings, why would you NOT buy P280 over Eleven Hundred? That’s why P280 got a value for money! Plus not to mention the “unofficial” support for at least some XL-ATX form factor. Sure, it’s a minimal design for a lot of people’s taste. But- how many manufacturers sell a tower as big as this under Rs. 10,000 INR/ $120 U.S./ £95??

The only point that didn’t let the case slide down to “not recommended” to give Corsair 500R some company rating is because it uses the same framework as P280. It’s as strong as P280.

But you need something more, you can consider CM Storm Trooper/Stryker. You get a handle beautifully bolted on the top panel itself, and you get all the fans you’ll ever need to start with- air filters wherever you need them- and it’s not as minimalistic as P280 it is. But CM Trooper/Stryker costs more than P280. But at least, CM provides an 8 EPS extension cable, not to mention 2.5” X-Dock on the front is a plus. But at the end of the day, it’s more on you and if you will utilize these cases to its full potential. P280 and Trooper are 2 cases that will be a lot preferred by workstation builders- and also hardware enthusiasts.

One comment

  1. i think with the same case design, they can provide 240/280 rad mount on the top this case and this case will become a stunner. its even kinda weird why would they not have mount grips on the rubber grommets but P280 is way too minimalistic design for my taste and I really hate the front panel door. No $100 chassis comes with no mounting for rads since everyone makes then now so once they do that they need to have a white black combo color type on the case. that will be an excellent stunner….
