The only real issue is reliability. Server versions are made to maintain as much uptime as possible, Windows Server updates don’t always require a restart (except Patch Tuesdays), whereas the desktop version almost always does and will do so without any warning. If you’re using it for home use, does that matter? Probably less so, considering downtime doesn’t cost you money it saves it if anything. Plenty of mom and pop offices use off the shelf desktop PCs as “servers” cause it’s more cost efficient.
