open air for me too.
GPUs are zip tied to racks.
the room is the case and the windows are the exhaust.

Started my GPU farms like the above in 2016 and never looked back - ease of maintenance is the key.
Dust is the only pitfall though - I gave up on this long time ago and most of my 470/480 rigs still running at peak non-stop eventhough they are bloody dusty and grimy.
Well ..... as long as critical parts still works fine like fans for PSU, GPU and CPU - will just leave them alone. All of them are well ROIed several times over, so just leave them alone.
ease of maintenance you say?
how about real time (powered on and mining) pulling off slow spin/not spinning GPU fans and re oiling-plugging back in fans? hehe
no need to keep the area squeaky clean, for me i'm just making sure dust build up does not come close to possible "harmful" level to electronics----> i just come inside the room semi naked with face mask and a blower.. blowing the dust that accumulated in the electronics (all powered on and mining)
