Case - I have a case that will fit ATX, EATX, and CEB boards. Its a generic POS. I might spring for a Silverstone raven if it turns out this one can not handle the cooling. Going to wait and see what happens.
MOBO: This is what i need help with. so i have the tv tuner in the old build. should i make this just my gaming rig and leave the Movies and what not in the old comp (old pc specs at the bottom). The old pc has issues i think its the mobo giving out. Is it worth it to spend the extra money on a 7 slot PCIE mobo for physx? will my little 8800gt even make a difference with 2 480's? if i do keep the tuner in the old pc the sound card will go in there too for the 7.1 speakers. Will it be worth a sound card for the gaming rig too? I'm at a loss, i know what i want to do just not sure the best way to go about it.
