Yep. I decided to do it. The day after moving the gopher server onto a 
NUC I decided to move the web server as well. Actually, that'll 
include the XMPP and MQTT servers as they all use the same SSL 
certificate. I've ordered a new NUC and that'll probably be my project 
over Xmas. To be honest, the existing web server is running well on a 
Raspberry Pi 3, but there's been so much software on there (mainly PHP 
related) that's been tried and trashed that it's all a bit messy. More 
later...
