I've always fancied a go at making a convection cooled PC. The plan is to cut a 6" hole in the top of the case and fit a good lenght (at least 2m) of extractor fan hose to it. This would run, as much as possible, straight up. I've never thought of connecting it to the outside but that would be good too. The idea is that the heat inside the pipe will cause the air to rise thus creating its own draught. With another bit of hose on the inlet we could have a balanced flue design!

Wherever the air comes from, try to make sure it's dust free so it doesn't all end up inside the case. Unfortunately, floors are particularly dusty and a bad place to have an air inlet.
