You must've done your homework, all-in-all a solid build, the psu is a little pricey imo.
That water cooling kit has got to go,
Apogee GTZ Swiftech Apogee GTZ Extreme Performance Waterblock
the 1366 bracket is $10 if it doesn't come with
get a good pump Swiftech MCP355 12v DC Pump
this is your best bet for a radiator Petra's Tech Shop
I haven't seen a water block for the 295 yet but I guarantee if one isn't out it won't be long before one is...
reservoir is really your choice on footprint, I know there's one made for the MCP355 pump that goes right on top of it, these parts are parts aspire (i forget the rest of his name) recommended to me and I'm planning on clocking an i7 920 fairly high. *cough* 4.5GHz *cough* of course I'll have more than a 3x 120mm radiator but that one will do you just great
anyways, with the water cooling this will turn out to be one hel* of a computer
