I probably just looked at the same sites that you did, but from what I've found, the built-in IR receiver won't work with Windows so you need to get a USB IR receiver. Hopefully that's wrong, but that's what I've been seeing.
Btw, I just got my first Mac Mini on Friday, and I have an SSD with Windows 7 already on it. Not to hijack your question, but do you know if I could put that SSD in as-is, or would I have to reinstall Windows? Thanks!
