Recently bought a Dell Optiplex 780 Windows 7 machine which, for all the investigating done, does not include Bluetooth.
Am also interested in picking up a keyboard/mouse combo, but a couple I've been looking at have Bluetooth.
Without having to crack the case open and install an additional piece of hardware, is it safe to presume that a simple USB/Bluetooth dongle will allow Bluetooth peripherals to play nice on said pc?
