One more thing,

If I already have a Logitech Wireless keyboard and mouse can that receiver be used? Or is that RF? Sorry, when it comes to frequencies and such I'm a total newb, put me inside a computer and I'm at home:)

Also this is the TV tuner card I'm going to order to use with MCE [Link: tigerdirect.com] It also comes with a remote so will I still need the MCE USB receiver?
