Looks good. I have a few suggestions though.
CPU: Great CPU choice. I would go with that.
Motherboard: Doesn't support SLi. Don't know if that matters to you or not.
Memory: I wouldn't get that memory. I've been told that Corsair's value memory is not good at all. I have some GEIL value memory and I'm very, very happy with it. It has the blue aluminum heat-spreaders on it and they look sharp! Check that out, it should be on Newegg. You also might want to go ahead and get 1 gigabyte of memory, you'll probably want it later. If you do that, you can get it in one stick and save a DIMM slot.
Video Card: I've heard bad things about XFX. Just a warning. Doesn't look like that card has had many problems though. I know XFX's AGP 8x 6600GT had a TON of problems though.
PSU: Looks pretty good. Don't really know about Enermax, though. I got an Aspire after many people told me they were a great company. I'm very satisfied with mine. Also, since you'll be running all those fans, why not bump it up to 500 watts and you can brag to everyone for sure, "My power supply is better than yours!"
Case: Hey! I got a 25 dollar case!
All in all, I'm likin' the system. This is just my advice, you don't have to take it. I won't be offended.
If you have any questions just let me know.
