I have this TV: Click Here to See
and I want to buy a new HP or Dell desktop but just the tower and also install a wireless card on the back of it, along with a wireless keyboard with a built in mouse like on laptops. Then I could do everything on my TV from the couch because the TV has a VGA port and other ones. Then using the remote I could switch it back to cable tv. Does anyone one see any hardware or technical problems with this idea?
