Hmm... once I get the money, I might just toss some SATA in that thing,
then. I've been VERY pleased with the 80GB 8MB cache WD SATA 150's running
on this PC... Any SATA cards you'd recommend? (also, what hacks do I need to
boot from them, or should I keep a teeny IDE disk around for the kernel and
