Old questions but no, Windows 10 pro/home doesn't make much of a difference unless you want to join to a domain. Pro also gives you some other business capabilities you're unlikely to use and BitLocker - which I like - but you probably don't need on a home desktop/server.

The only other thing I see as a difference maker would be Remote Desktop... it appears to not be available in Home unless you follow some lengthy workarounds (of course there all alternatives all together but... still a workaround).

Finally all this being said, if you're able to find a good deal on Win 10 Pro - I'd still go with it

There are lots of listings on eBay for Win 10 Pro keys and 'recovery disks'. These often come from pallets of older office PCs that are being replaced or scrapped.

I got my copy of Win 10 Pro with the CD for $29 and it activated without any issues (and it was the actual disk, not a copy).
You can get just the Win 10 key for a few dollars:

Just run Debloater or a similar program after install, or you could use the installation designer to deselect all the extra Windows garbage that you don't want installed.
