An interesting case. Not a perfect fit but probably not too hard to adapt it to fit.

On a side note: The pine boards are $15 and I think the allwinner issues have been worked out. I’m not sure what the euler bus is though. Only USB2 but I see a lot of pins there.
Just get hammond box and do customize it for the connectors rather a box made for other plus waterproof case i don’t know who want to go swimming with there limeSDR.
Haha! Swimming with my LimeSDR. I read a comment somewhere and one solution to bad loss was to put the SDR at the antenna and run the ethernet to the lab/office/shack. I guess for lime it would be USB3 but I would guess the length would be limited.
