I want to play SC2 and possibly Cata when it comes out, looking for specs i should look into for a tower. I got a monitor and all that and don't mind trying to build my own from scratch. Any ideas suggestions for what specs i should look into getting? thanks guys and gals!

7,200 rpm main hard drive at least or an SSD by Intel if you can afford it
Core i7 920

LGA1366 x58 based motherboard (ASUS is a good brand)
6x2GB Triple Channel 1333Mhz DDR3 memory.. OCZ is a good brand
LianLi Alluminum tower case would be good.
I'd suggest an ATI 5870 or a couple smaller cards in SLI.
Around a 800watt power supply should do the trick
If you're looking for a good CD/DVD burner, Plextor is the best out there, but I've also had a lot of luck with LG.

Thanks bra my buddy chase (or blackrage if you ever met him on his druid in game) can get me a good deal on a tower at sam's club for about $450 with his discount. I cannot remember the exact specs but it sounded nice probably just need a video card upgrade after I get it.

Just make sure it has at least 1 x16 PCI-e slot and you'll be ok. The system itself will most likely be a bottleneck to a fast video card, but its a good way to save some money.

Depending on the specs, I'd recommend a 5750 or 5870 ATI card

Much appreciated mang!
