I know it's not Apple but, I picked a fair bit of old Sun/Digital gear up from eBay (for $40 Australian):

- AXIL 320 (Sun SS20 clone) with separate removable and fixed storage (and it's on wheels!);

- DecStation 5000/125 (looks complete);

- DecStation 5000/200 (may be missing stuff);

- DecStation SCSI storage unit;

- Numerous old Sun SCSI storage units (some are huge);

- Many SCSI cables, monitor cables, mice and keyboards (mainly Sun);

- An IBM Model M keyboard (looks functional!);

- A few Digital and Sun monitors (huge).

Let the tinkering begin!

Edit: and a 3COM 10Base-T repeater (16 slot backplane with serial port and 5 x 3 port ethernet cards) - anyone know what this would do?
