"DeviceGuru.com has been alpha-testing Boxee’s
media center platform on our Ubuntu-based Black Tower desktop PC
for several months now. It’s great for streaming movies and
TV episodes from Comedy Central, Youtube, Hulu, etc., and for
enjoying A/V content located on your PC or other local source. A
few screenshots showing Boxee running on the Black Tower, which
currently runs Ubuntu 8.10, appear below."
