Ha! How about HiFi literally in the wild?
Above is a Roon server I built for outdoor use and took camping. I used an i7 NUC + Roon R.O.C.K. and stored my music on an internal SSD. The server is routed through a Ubiquiti edgerouter to a mesh WiFi antenna.
I used a portable basketball hoop (without the hoop part attached) to mount both the antenna and the weatherproof enclosure. The enclosure itself is totally self-contained, with 2 fans to pull air through and help the system cool, and 2 ports on the bottom for ethernet (router to antenna, w/ PoE) and AC (from a battery + inverter, recharged via solar).
This setup worked perfectly for 4 straight days of camping and had about a 500’ usable range for streaming music. I mostly used tablets w/ Roon Remote as the endpoints, and bluetooth speakers as outputs from the tablets. However, the source music was all lossless FLAC.
