the corsair ram he has listed doesn't have huge heatsinks, so they shouldn't cause clearance issues.
some suggestions; you could go with this set of ram
Newegg.com - Mushkin Enhanced Blackline 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model 996679
rated to run at the same speed and timings as the corsair set but it doesn't cost as much (it would still end up being less expensive even after the corsair's rebate)
you could get this combo with the cpu and that xfx 650w psu clown had listed above
Newegg.com - Computer Parts, PC Components, Laptop Computers, LED LCD TV, Digital Cameras and more!
either the antec or the xfx would be good choices, but with this combo you save money while getting a modular psu.
also, you might be inclined to spend 10 bucks more on evga's lifetime warranty on this card
Newegg.com - EVGA 01G-P3-1371-AR GeForce GTX 460 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
(comes with a free game d/l too).
