I am not trying to prove you wrong here or agree with you overally much, however, I think the CM-690 has been sold correctly and if you are this dissappointed with the case that its just not the case for you rather than being a bad case itself.
This is probably true of the majority of cases to be fair.
This.
I think the case is really well speced and for the money you can't go wrong. If you compare this with something like the antec 900 (another fan favourite) this its miles ahead.
I'm really happy that I can actually fit all my water cooling in such a small case. There's no other case out there that can offer this without costing a lot more or being bigger.
It can only fit all my water-cooling in because I spec'd my water cooling to fit in it. If I'd bought a 360mm rad I'd have trouble fitting it in and I imagine most people would.
Personally I don't think someone could pay me enough to get one of these cases again. I much prefer my HAF 932.
It might not all be the case's fault. I bought it to put a new build in and I'm just disappointed with the whole lot. So since I view the whole lot negatively I think the bad points about the case just seem to stand out more than the good ones (which people seem convinced there are, but I can't see them).
the rest of the PC spec for those interested is:
CM 690 II Advanced
AMD Phenom II X6 1055T @ 3.8GHz - Water-cooled
4GB Corsair XMS3 DDR3 RAM
Gigabyte GA-880GM-UD2H
2GB 4870x2 - Water-cooled
1TB Samsung F3
LiteOn DVD-Writer
Corsair TX750W
Most of the water-cooling parts are XSPC (with some Fesser and EK bits)
The Samsung F3 is nice, as it the DVD drive and can't see anything wrong with the RAM. Undecided about the 4870x2.
The rest of it I'll probably end up getting rid of and getting something decent.
If I liked the rest of it I'd probably have overlooked the cases issues.
Still, I don't think it hurts to point out what I didn't like about the case, give potential buyers a different perspective.
