I started on Elitedesk 800 G1s when Raspberry Pis got hard to find and expensive, and I now feel they are better in every respect if you don’t need the GPIO pins.
Every time I open them up to upgrade something I’m impressed with the level of engineering. There are quality manufacturer manuals for them, the cooling is good and they look great
Been running Home Assistant and several other apps on a G1 Mini for the last 4 years. Upgraded from a Pi and while I still love Pis the performance difference is night and day…
