Need help choosing a case!!

Hello everyone, I'm building a new comp. I'll use it mostly for gaming but I'll not oc my setup or anything. Here is my setup.

MSI P45 Platinum DDR2 1200MHZ 1600(O/C)FSB MB
Core2 Duo E8400 3.0 Ghz 64Bit 6MB L2 Cache
4 GB (2x2) 800Mhz DDR2 Plat. PC2 6400 CL5 RAM
Samsung 750GB 32MB SATA2 7200RPM HD
MSI HD4850 512MB GDDR3 256BIT

I'll buy one dvd-writer, use the ob sound card. Now comes the hard part for me. The case:

How many fans will suffice for this setup. I mean there are 1 fanned,2 800mm fanned,2 1200mm fanned, 1 800 1 1200 etc etc.
I'm getting a little dizzy here.

Also for psu, as I'll not be oc'ing or anything will a case with its own psu(there is a Cooler master with 430w-CAVALIER CAV-T01 430W ATX) be enough, or should I go and buy my own psu.

And my last question, will the cpu's own cooler be enough for my needs or should I buy a new one?

I thank everyone in advance.

for proper cooling of newer gaming machines, I tend to suggest the Antec 900

I actually have its little brother, the Antec 300 and it is still a decent sized case with the larger fan blowing air out the top and the fans in from the front

Yeah, I'd recommend either the Antec 900 or 1200. The 1200 is very expensive these days, but I have my eye on one too for my pending new build.

Go Lian Li, you can't match it's build quality anywhere.

If you want cheaper look at something like their PC-7 or PC-65, if you want something a bit fancier, well they have plenty of other options.

Also I would suggest that you do not use the psu that comes with the case, although antec PSU's are fine, but generally PSU's only come in lower end cases to keep costs down.

Go find yourself a nice 550-600w PSU for that rig, it will give you plenty of overhead for some upgrading if you need to. There is a sticky in our PSU section to help you find a good brand. (Personally I run the ST60F from silverstone, its on sale quite often and can actually get pretty affordable).

Personally I have a Coolermaster CM690 Dominator, just recently got it and it is a smashing piece of kit. Not too expensive either. Can't say a bad thing about it and has more cooling options than you can shake a shitty stick at.

I'm actually building a new rig these days and I'm leaning for the Antec 900. Even tho my current CoolerMaster Centurion 5 has been more then amazing. It has a brilliant build and the air flow is more then I could ever hope for + the mesh means it collects very little dust when compared with other cases (I compared with a friend's NZXT BLACKLINE and it had about half as much dust) and the CM690 is basically the next gen of it.

It's a close fight...We'll see which one eventually buys me over.

My old build is in the same Centurion 5 case, and my current build is in an Antec 1200.

I think the 900 has the same filter system as with the 1200.... washable filters that are really easy to get out.

It's pricey, but I would definitely recommend it. (@OP)

What about the 902? The looks of the 1200 in the size of the 900

I like it anyhow
