Sorry for so many threads about this, but I'm really indecisive and I just wanna make sure I get the best out of my money.

9800GTX or 4870? I'm kinda leaning more towards 4870.

Antec P182, Antec 900, RAIDMAX Smilodon, or NZXT Apollo? I'm thinking the P182, but it's expensive.

Will update tomorrow.
