CM 690 III came in a plain box, but it was marked as a sample. I am not sure if the retail version will have specifications and case design illustration on it, but most likely the internal packaging is the same.




The case was wrapped in plastic with 2x blocks of Styrofoam blocks wrapped in plastic and a manual.

The specification of the case are as follows, but do note that you can mount up to 10x 2.5″ drive. The case is made of steel, but for some odd reason, CM didn’t mention that.

The PC case weighs 8.7 kg. according to the specifications, without the hardware mounted on it. Keeping that in mind, its important that the PC case is strong enough to accommodate a lot of hardware. 400R was good enough for what was worth, but the case structure wasn’t strong enough.

That’s why Corsair 500R was marked down, because for the premium over 400R with the same basic framework was not worth it, especially considering that price range of Corsair 500R could easily allow you some of the HAF series cases. Even the good old Antec P280 was a better choice.

I’ve said the following in Corsair 500R review:
The only issue I have is that the case is weak, and packaging doesn’t really do the justice of protecting it properly. I haven’t taken a look at the 400R yet, but if its the same case design and built quality I am very disappointed on the 500R because it commands an extra premium. It’s not the best case Corsair came up with. The front panel design is nothing new, Lian Li did it with K62w and Antec pretty much has it on 1200 Full tower. Both are solid steel cases and both are very strong. 500R is more designed to be a mass-produced model to go head to head with few best selling cases for the price point, but it’s too expensive and not really worth the risk. The weight of the core configuration does hold the case together (In layman’s terms: imagine it’s like a packaging box- like the case’s packaging box. It’s weak because its empty but once the box is filled with stuff and properly taped on both ends, it does hold the basic cube shape and they don’t wobble.) and most of the wobbling does stop (despite filling it up, and when you remove the HDD case, the case does tend to bend).

Why am I bringing up 400R and 500R? Because I’ve 690 II Plus as well, to which I’ve said the following:

I appreciate CM 690 II Plus, but 400R is more “polished” product, although their I/O section is weak.
