I run mine on a used Adlink MXE-5401 industrial PC from Ebay ($2000 new, got mine for $65). I love these boxes. Used in manufacturing, transportation, etc. Cast chassis, fanless, all solid caps, ton o' ports. They even tack the SODIMMs in with a spot of glue. Meant to be set/forget.

Love these units so much, I bought 3 more of an older series with i5s just to mess around with, $45/each! Got one running as a 5G AP, another running KVM and the third, Openmediavault.
There's a new, current production MXE-5500 with i3 on the 'Bay for $150 now, no affiliation. Would love that instead of the i7 I'm using now.
