I ended up ordering this one that Cybjorg linked. I wanted to get the one Mark recommended because of its built-in power supply, but couldn't find a US distributor and also was concerned about heat and noise. The one I ordered has a large quiet cooling fan instead of a small noisy cooling fan. Since I'm in the process of quieting down my system (I also just ordered this as the final step in quieting down my PC), I was concerned about that, you see.
