If you use one of the smaller backplanes, you can get an 11/23+ ( /73, /83
etc)into a old desktop PC case (use RQDX3 and an RD drive, along with an OEM
power supply). The worst you'll have to do is make up an RQDX3 to drive
cable (no space for the interconnect board). You'll also need to build a
watchdog module, but that's only a dozen or so parts.
