Well, this isn't much cheaper, but it does shave off a little bit, while offering a much newer, better motherboard, and more reliable power supply that's likely to last longer due to a better internal build quality. That price is also BEFORE any applicable rebates, so it might be even less costly in the long run.

Those W1 series EVGA power supplies are junk. If you buy an EVGA unit you pretty much want to stick with the B2, G2, P2 and GS units, which are much higher in cost and capacity than what you need for this build. Avoid the B1 and W1 units.
