Buying xbox one with broken motherboard

Guys, I have a question. A friend of mine has Xbox one, but with a failed motherboard. So, I am wondering how hard would it be to order a new motherboard and replace it by myself? I can get a motherboard on eBay for around $60, but is it hard to change it?

No, it’s not hard to replace a motherboard. You can find good tutorials on how to change it without any issues. Go for it, my friend!
