You can find them cheaper than that even. I picked up an old statmux
locally for $20. Had to strip the guts out, but it had something like 25
6502s running it, along with some oddball EPROMs and other interesting
chips. I passed them along to someone who could put them to use, and now I
have a nice 72" inclosed rack with front & back doors, removable sides, and
two fans in the top, one of which doesn't spin up. A **LOT** cheaper than a
new rack!

Alas, the VAX 6320 and DEC 3000 800 won't fit in the rack, so the basement
is never going to be truely quiet without a power loss. ;)
