Everybody loves Vuvuzela, I even made an Android app for it: http://www.androidzoom.com/android_applications/sports/vuvuzela-soccer-world-cup_hyzb.html
More than 10000 downloads in 3 days! People will soon learn how to play Vuvuzela at musical school :)

Geode is a bit underpowered but for a file server and torrent daemon, it's plenty enough. Comes with an internal 80gb hdd but can also boot from usb, btw 4 usb ports is really great. Fanless and uses less than 10 watts! It also comes with ubuntu pre installed.
