I think this is different than the "should i air or watercool" thread, so I'll try to be as concise as possible, as I've found little to no info on this while googling. For school, I'm about to submit a project proposal to the faculty for a render farm: The system itself will be 8-15 lower-end PC's linked together to a main computer to perform rendering operations for the art students. Render farms can get hot... the ambient heat caused by close to a dozen PC's can sometimes raise the operating temperatures to dangerous levels, especially on a system like this that will probably be utilized often by the hundreds of modelers at this school. So, instead of individually-cooled systems which would possibly become a hassle in and of itself, I came up with the idea of placing all the systems into a fridge to keep the temps down. The thing I'm worried about most is the moisture in the air in normal residential refrigerators that could cause some very bad and very obvious problems. Unfortunately, most commercial applications either lack the storage space, are way too big, and they all cost more than a used car. If anyone might have any ideas or suggestions for this project idea of mine, I'd be extremely grateful. Thank you.
