If you haven't gotten the mobo/cpu, I would also suggest that you take a look at MWave.com, they have motherboard bundles and will assemble and test them for you before shipping.... I have had many many mobos come to me that way, and they have very good CS and return.
lots and lots of combos to setup there... my only issue is I like better quality ram, I don't know if they offer that, but it would be worth a call...
Most higher end RAM comes with a lifetime warranty - so keep that in mind, as I have had RAM fail on me, and they honor those chips.
