open air for me too.
GPUs are zip tied to racks.

I once thought of using some of those enclosed IKEA clothes racks. They are sold on Ikea (I couldn't find it on their website) for like $25 or something. The idea was to position the rack near a window , cut open holes at the back, near the bottom for intake, and one for hot exhaust at the top. Then place rigs inside it. That way it would be an enclosed system, while still using outside air for cooling. It also wouldn't look insanely ugly.

Never got into executing this plan though. For now I have my miners in the patio with box fans blowing at them.
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) 
LOL nice mental image there.
