Well, I finally bit the bullet, pulled the trigger, whatever, and ordered the parts. In case anyone is interested:
Motherboard:
MSI X58 Platinum - over the Pro version for SLI, in case I ever want to get a second card
CPU: Intel Core i7 920 - bought at Micro Center, where it was going for $229, a full $50-60 cheaper than anywhere online
Memory:
6GB (3x2GB) Corsair DDR3 1600Video Card:
EVGA GeForce GTX 260 Core 216 - I figured, what the hell, might as well

It's about as high as you can go before the price curve starts getting really steep
Hard Drive:
Western Digital Velociraptor 300GBPower Supply:
Corsair 520HX - I had gravitated towards this one already, and read a very favorable review of it on Tom's Hardware, which put it over the edge. I'm hoping that 520 will be sufficient, which it should be...
Replacement HS/F:
Noctua NH-U12P - I ended up going with this one over the Arctic Cooling model for a very silly reason - Newegg had it. Plus I read an extremely favorable review that made it sound like it even better compromised between cooling and noise levels, by doing both almost as well as any other air cooler on the market
The following are the carryovers - not much, but that's what happens when your motherboard and PSU get fried and the rest of the parts are cannibalized
Case:
Lian-Li PC-75 - This case is enormous - far larger than I need by about 11 drive bays - but I still love it
Optical drive: some high-speed SATA Plextor drive
Monitor: I love my Dell 30"

So that's it. I'll take a few shots of it when I get it running, and give my impressions of the performance. I'm hoping to overclock it a little bit, maybe get it above 3GHz, but I'm not going crazy with it.
