Went to RePC today - they're a computer recycler here in Seattle - and found one of these beauties:

Cool huh?
Hey - it was only $25.00 US. How much fun is that?
I'm gonna try to put some version of Yellow Dog on it. Not sure which one yet. Plus - I need to buy a hard disc for it. Luckily, it takes standard IDE, instead of SCSI.
I'll keep you posted on how it goes.
UPDATE: Looks like it might be Yellow Dog Linux v3.x. See here:
