Other than using the samsung spinpoint F3 1TB instead, which is the same $59.99, i think you are pretty much there.
Generally you don't need an athlon x4 for things, but at 85 it's pretty much a steal.
Generally I would advice against the open box mobo's. But it does save you a few bucks.
Maybe it will work for this as you also added the 2 sata cables.
Is the Samsung better than the Seagate? Seagate's got better transfer speeds, doesn't it?
Does anyone have any experience with Newegg's Open Box stuff? It saves me $20, is it not worth the risk?
