The best case out of these

I would suggest the Centurion 532 or the 534.

The 532 has a 120 mm intake fan in front of the HDD and space to mount a 120 mm exhaust. It has a duct for the CPU HSF.

The 534 on the other hand seems to let you mount 2x 80 mm fans (one front and one side) and has a 120 mm exhaust.

What CPU and and GPU are you putting in?

I personally prefer the 532 but you might want to use the 534 if you require more cooling.

If you look at the lower left pic on Newegg, you can see that the Apevia has a place for a front fan.
I've used three Coolermaster Elite cases this year. They're a step down from the Centurion; they have the space for it, but the front fan is not already present like it is on the Centurion. They have side air ducts also. These weren't performance boxes, but they are dual core, and have not had problems. My wife's is barely audible with its stock fan.

Forgot to tack this on...

If you end up waiting to build watch for killer deals on cases like the Antec P180(B). They are great at MSRP and a real steal if you can get them in the $70-80 range.

I'd wait about two weeks or so before you buy that 8800GTS. I know a guy who knows someone inside ATI that is in the know... he isn't leaking any details, but I think you should consider this one word:

R650

I got a P180 for $79 shipped from Newegg... I'm still excited about it.

The only thing I'd say and it's been mentioned, go with a case that sports 120mm fans and not 80mm, you'll end up with a much quieter case. That's one grip I have with many cooler master cases, is that many of them still use 80mm fans while most other good case maker have move up to 120mm .

Well, I don't know all the exact details about R650 or what a release of it would do, but I know someone who might could get me some info for you... although I may end up banned before I can get it to you... we'll see though, I have a second username if that happens.

Here's my thoughts:
534- Move the side fan to the front and you'll have a case that should perform well in mild OC situations. That will move air better than a side and rear combo. I don't remember what size the front will take... I kinda think it is for 120's only but I could be wrong. My CM case (Praetorian 730) will take 2x80's or 1x120 in the front..

532 - Only 1 fan and mesh front. Should perform alright but really could stand to have a front intake fan. The mesh front will result in a slightly louder case than than the 534.

I don't know about any sales, but there were some huge Black Friday deals last year at the egg. Sign up for their newsletter... you never know what type of deals are going to appear. That's how I got off an extra $30 on my P180B.

I don't know what all you're buying so here's some additional recommendations:
CPUS: Buy it now
RAM: Especially buy it now. Prices are going back up and it should still DDR3 can match DDR2 in performance.
Motherboards: whenever
PSU: You can buy it now or then... you're bound to end up with a good deal one way or the other.
Case: Black Friday typically has some insane deals. It's an excellent time to buy cases. I don't specificly remember, but I believe that the sales generally are a little bit of everything here and there. Cases, PSU's, CPU+MOBO combo's... you never really know.

I didn't see that the 532 had both fans... my oversight. Both cases have side vents. The 534 shouldn't have a front fan but I would definately move the side fan to the front. Both would be nice cases, it's really a matter of preference. I'll stick to my guns and say that the 534 will be a touch quieter, especially if you have any type of high-RPM CPU fan.

Well if black friday can hold insane deals on everything I'm buying, then is there a reason not to wait? On the CPU I heard that in a couple of weeks prices are going to go down a little bit and settle and the GO stepping will become more abundant...I mean think about it, if I buy this stuff now and on black friday I could have saved $200, wouldn't you think I would be sad? And there's no reason to build this rig now if ati is releasing some new stuff soon....argh this stuff is perplexingggg!

Remember if you always wait for the next best thing, you'll never get any use out of your computer.

EXACTLY!! You always say what if I wait some more, or what if I go up $10 and get this better thing, and it keeps on going...and going...and goingggg!
Yeah I guess I'll wait for R650, but the question is, will they be priced accordingly?

I wish I could tell you how much the R650's were going to when they hit... but I'm only one mortal man that knows a guy that knows a guy... I'm just going to say go ahead and buy the rest of your parts now and wait for the GPU... there really is no telling how it will be priced or how it will affect the 8800's pricing.

Not really sure where that fits in...
