Totally! There are a ton of used workstations on eBay for cheap too. I got a Lenovo M715q with a Ryzen 5 APU for under $100USD. I can’t afford not to have a garage desktop at that price.
I started picking up Used Tiny / Mini / Micro systems. I currently have a Lenovo M910q with an i7 7th gen running my frigate dockers. I got it from a local second had PC shop, but you can find them on eBay and Facebook market place often.
Asus makes a NUC like box, and there are Aliexpress brands like beelink etc.
I'm shopping for servers right now and was distressed at the NUC situation (news to me). 4 months later your comment and this link are still helpful. Thanks!
