Pardon my ebay posting....
I've put up a bunch of HP 9000 and related on ebay. It's under seller name w9fz.
Hopefully this link will work:

Presently, there is a G40 and G50 with a G30 and G60 to join shortly. Loads of SCSI drives. Even 7980XC tape drives. Some HP-IB storage drives. HP 9000 rack accessories.
More going up soon to include 5 or 6 loose HP 3000 cards in anti-static bubblewrap. And more.
Thanks for potentially looking.
