I get the following for $260 delivered:
Refurb Intel 915G ATX mobo w/ embedded video/LAN/USB
2.8GHz Celeron D processor
2 x 512MB DDR2 RAM
128MB USB flash drive
300W power supply
bit of plywood to mount everything on
cheap desk fan to blow air across everything
I suppose for $300 we could go the luxury route and get an EIDE hard drive for it, too.
Hmmm... Wonder if two of those would get into the same folding ballpark as your dual 3800?
