I would really prefer not to use a USB adapter, and would rather have it built into my mobo. What should I be looking for: adapter, card, drive? I have no clue.
They make pci cards for bluetooth that can be put in the mobos pci slot. Newegg.com has them, most of these don't cost very much. I don't see anything wrong with the usb adapters though as usb nowdays is a lot faster than the original usb 1.0.
