The case is a bit small.....I'd recommend one of the following pairings:
Antec 1200 V3 w/ CP-850 PSU
Corsair 500R w/ HX850
I'd up to the Hyper 612 PWM or the Scythe Mugen 3
Im partial to the Seagate XT designshttp://benchmarkreviews.com/index.php?option=com_content&task=view&id=708&Itemid=60&limit=1&limitstart=10
I'd use low profile RAM w/o any unnecessary tall toothy heatsinks
ATI was oft coined to mean "Always Trashes Inventor" .... It gets real important if 3D max is gonna be in the mix as nit having an nVidia card, means ya can't use any of the CUDA plug ins.
