Just a minor update, but it turns out it wasn't the PSU that died. My motherboard actually was the thing that decided to spit its ghost. Never had a m/b go on me before, but I guess there's a first for everything.
Just ordered a bunch of parts from Newegg, which won't get here until next Tuesday or Wednesday, so won't be able to catch up with you guys this weekend, but maybe the following weekend if all goes well. (You are still hosting each Sunday night, right Steve?)
Upgrading to a Cord 2 Quad Q6600 and ATi HD2600 Pro 512MB GDDR2. Should be a nice bump up from the old Athlon XP-M!
