This would be perfect for me. I have a pile of Macs with various individual hardware failures that would never have been replaced had I been able to easily swap out new parts. (Not to mention the ridiculous hardware failure rate of Macs.) I also hate having machines with that one piece of hardware that doesn't work on *BSD, because getting it to work is such a pain. It would be much easier to swap out the offending hardware for something more compatible.
