Sorry, I am at work and my PC only supports English input.
Mac mini is nice but IMO it is not the best media server option. I use a QNAP NAS at home. It is basically a Linux server with 8 TB harddrive space. I have a Twonky server running on it with full UPNP support. The front-end player is T+A Music player. I also use an Ipod Touch as the remote control.
