RaQ 3i = 1 300 MHz AMD K6-2 CPU, 1 ATA/33 HD, 512MB RAM max

RaQ 4r = 1 450 MHz AMD K6-2 CPU, 2 ATA/33 HD (RAID-1 mirroring), 512MB
RAM max

RaQ XTR = 1 850 MHz or 1 GHz Intel P3 "Coppermine" CPU, up to 4 ATA/100
HD, 2 GB RAM max. Completely different beast from the RaQ 3 and RaQ 4.

Sketchy at best.  That mobo only has a single IDE connector and a single
power cord, so adding a 2nd drive would be a bit "iffy" IMO.  It might
work just fine, but possibly not...

In theory you can drop in a K6-2 450 like the RaQ 4 uses.  AMD
themselves said the 550MHz K6 was "flaky" so that's why we topped out at
450.  Best to stay at 450 or below.
