So, for one of my next upgrades, after having done the AirPort Extreme install (and because my hard drives are brand new, so no point in SSDs just yet), I want to see if I can get Bluetooth working so I can pair it with my Mighty Mouse that's just sitting here and a new keyboard to replace my aging and discoloring white one. But I want some opinions/suggestions... Apple says in the documentation that if you didn't get the module installed, then to go the USB route (and I see a lot of people asking about them all the time). But then there are the actual modules that are floating around to install. Which option would be better? Considering that the keyboard and mouse would be not even an inch apart from the tower and that if I would go the USB route, that it'd have to be in the back since I use the front port. Thanks.
