I certainly enjoy my Tandem-badged, stylishly-all-black Challenge L.  It has
_lots_ of expandibility, far beyond anything I expect to need.  Subject to
OS limitations, you could have 8 CPUs and 4 GM RAM (or maybe 12 CPU and 2 GB
RAM), and more SCSI than you could afford to run.  I think you can put an
IO4 board in each of the 5 or 6 VME slots, and each IO4 can handle 5 SCSI
chains (FW/HVD or F/SE) ... so, maybe 25 SCSI chains of 15 drives each.
Something like that.  Of course, the Onyx version uses some of those slots
for video.

The bigger XL units are even more expandible.

I expect they will be around.

Pick a spot in a cool climate with cheap electricity, and just let your Rack
Onyx heat the house.
