I'm using a case from an old Sun workstation.  The "lunchbox" series.  Same
for my Thunderbolt GPS.  The cases stack nicely.  Painted all my old Sun
cases bright electric blue.

Actually the 5.25" drive case seemed like a better choice to me. I picked up an Iomega external optical drive in a plastic case for a few bucks. Hard to get open (hidden snap latches) but the plastic top was easy to machine with a Dremel tool and knife. After making a large rectangular hole in the top I mounted a big honking heatsink to it and, using long screws, fastened the PCB mounted Rb to the heatsink using a thermal gap filler pad. A switching power supply sits in the bottom to the rear. The case front and back had grooves just right for 0.062" PCB stock, so I easily made custom front and rear panels. Rear holds AC power connector & fuse, front has power switch, 2-color LED (Red = on, Red & Green => Yellow = Locked), 10MHz and 1pps BNCs, and a 9-pin D-sub wired for standard RS-232.

I am a fan of old stamped sheet metal mini-PC cases, and also a fan of the
clamshell "A/B" switch cases.

Usually the PC case is thin stamped sheet metal but often has a plastic
fascia that goes over the sheet metal. They have lots of ventilation holes,
unlike the clamshell A/B switches which tend to be thicker metal (didn't
need stamping for rigidity) with fewer holes. If I need a DB-25 or DB-9
hole... the A/B serial switches are real attractive because most of them
have that kind of holes and sockets in them already.

Usually I just pick these out of the trash but if need be they are only a
few bucks new.

One of my favourite cases for housing projects is to use an HP 37203 HPIB extender. Remove the PC Board and you are left with a power supply that is suitable for many things (or remove if not up the job), plus there is a BNC connector on the back side plus a spot where the GPIB connector poked through which can be repurposed for a D connector suitable for the task at hand.

I pick these up whenever I see them at surplus places, online, or at swaps when the price is right. They can be had at such places for $20 or so but eBay prices tend to often be much higher.

I've actually got my GPSDO in one of these, but there's no ventilation for cooling, so I thought I'd look for something else for the Rb standard.
