[Noisebridge-discuss] Storing a server, outside?

[Mark Cohen]

I concur..

I worked on the Jhai PC project (Pedal Powered PCs in Laos) .. Our  
machines were (old) PC104 based stacks.. Very little ventilation was  
necessary.. The thing we were most worried about was humidity.. (When  
I was there, it was 100% humidity and 95+ deg f)

If you have something inside the box forcing air out it is a good way  
of keeping most dust and particulates away from the computer.
