I don't know if you have an old (probably just works for Macs) computer with a functioning CD drive. But if you investigate the Remote Disc feature offered, then you might save money. My understanding (I don't claim any knowledge if I'm right) is that you can access a disc inside another computer on your network remotely without actually putting that disc into your computer (that doesn't have a physical disc drive).
"does anyone know if it is possible to use an old CD/DVD drive out of a PC, and just get like a sata to usb and then some sort of power adapter?
would that work?"
It will work just fine.
You might look for a 5.25" enclosure, to put the drive into.
I've burned hundreds of CD's with an old CD burner I found sitting _on the curb_ in a discarded HP tower. Pulled the hard drive out of it, it still works as well!
