Not long ago I discovered Mini Pcs and have begun to use them frequently.
Thy're keen, not terribly expensive, and run full Ubuntu with lots of ZIP.

I have:
a BeeLink Ser 5 with it's SSD increased to 2TB running Ubuntu, Miranda,
PHP, Perl, and, Zoneminder with 6 cams.

I also have a BeeLink running Ubuntu on my test bench, which compiles Arduino
sketches, etc.

a BeeLink Ser5 MAX 5800, with 4 TB ssd wich I will move CAMS to.

I have a KAMRUI running Windows-11 which I use for tax preperation, and 
downloading our GPS maps, etc.

I am running a KVM in my office for my workstation (Ubuntu), our main firewall 
(Ubuntu) and server, and two Minis mentioned above.
