Sure! I got them from eBay for around $120 each. They are 4u rackmount 
industrial systems that use a backplane. The actual motherboard conforms 
to a specification called PICMG. If you search eBay for it, you will find 
CPU cards that contain various processors, and backplanes. The actual 
backplane contains PCI controllers, because PCI can only have 5 slots per 
bus.

Man are used in telcom setups, industrial automation, and what not. The 
ones I found had 19 PCI slots, and perhaps 2 ISA.
