I feel your pain about cases.
I started out with a custom-made-for-me LX-6A19 & it started going downhill from there.
I'd always loved the looks of the LL V1000B, but didn't want to pay the premium.
I bought a CM 690 back when there were practically giving them away. It was ok...nothing special...made cheap, imho.
I finally found a pre-owned V1000B that had been slightly customized & purchased it. I wasn't real thrilled with my temps, so..........
I found an older Alienware case...really cool looking. I think it was the MJ-12. Well built, kept the hdd's cool, but didn't help the cpu temps.
Next, I bought a P180B back when they were dirt cheap...then a Sonata III. Again...they were OK, but nothing special. The P180 cooled a little better, but the side panels were cheap & broke easily.
I found a Stacker 830 at a really good price...again, seemed to be made cheap & wasn't that much better with cooling.
Back to my LL.
I continued in my search for a case i'd like as good or better than my LL when I came upon a deal for a Coolermaster Sniper. I thought this would be it...big azz fan on the side, front & top. Excellent cable management. Nope. Wasn't impressed.
Back to my LL.
All the reviews in the world won't help you make up your mind...believe me, I read & re-read reviews on the majority of these cases (save for the Alienware), but in the end I stuck with a case that I always liked even though it didn't get glowing reviews.
What i'm trying to say is get a case that YOU like...one that YOU'LL be happy with. Don't continue spending $$'s on something you won't be happy with...just spend them on something you will.
With that being said, after owning 3 CM cases, I seriously doubt i'll see another in my future. They just don't seem that well made, IMHO.
