Let me put in a good word for
Newegg. I'd heard about these folks on both the
AV Science forums and
AMD Zone. Their prices always seem to be among the lowest. They sell lots of OEM stuff, so most drives will come bare.
I just ordered stuff for my own homebrew rig from them a couple of weeks ago. I'm very happy with the result. Good e-mail communication, prompt shipping -- took about a day from when I put in the order to when it actually shipped -- low S&H rates compared to other on-line stores, and everything arrived well-packed and in good condition. I'm pretty happy with them, and I'll buy there again.
