The liquid-cooled beast I had at Warpstock is running on a Tyan S2885
AMD chipset-powered AGP board... been running since late 2003 on that
hardware, just not in that box.  The S2882-D is out for repair to the
on-board SATA ports at this time (they've had it for WEEKS!), but when
it comes back, I'll reinstall it into the 4U rackmount, drop in a bunch
of drives, and start beating up more hardware for eCS compatibility... 
I'm especially keen to see if my new LSI MegaRAID 8x SATA controller
will be recognized.

The dual-core Athlon64 4800+ is on an ASUS A8N-E motherboard with its
PCI Express chipset.
