No need for cables, and no need to have that tower sitting next to your monitor or TV.
A Home Theater PC is one of the coolest things you can add to your setup. It lets you access any content provider you want, play back digital media files of all types, and even play games. It can also be a real eyesore.
The problem of course is that you need to have the PC near your TV to make it work. Depending on the size of your PC, it can make placement a real pain.
The latest graphics card from KFA2 doesn't have VGA or HDMI outputs, but sports an antenna array that allows you to connect to a monitor or TV using WHDI.
You can get around 100 feet of range out of the KFA2 GTX 460 WHDI, which lets you put your PC just about anywhere you want. Pair a wireless mouse and keyboard with it and you've got a winner.
