Wow, this goes against Betteridge’s Law of Headlines, but absolutely.
I’ve got a small stack of 1L PCs running a ProxMox and Kubernetes cluster and it’s been perfect. Highly recommend. I’ll probably get one for my wife’s desk when she sets it up as it’ll do everything she needs and more, and it’s tiny and you can get em cheap lightly used.
Any tips on finding cheap used ones, other than scrounging eBay and the like?
Find a brother in law that works in IT. I changed his brakes and he gave me three Optiplex micros that were e-wasted from his work.
eBay, Amazon, sometimes you can snag deals when they release newer versions, they actually had a few on Black Friday/Cyber Monday.
Tbh, I got mine in a pack of 4 on eBay (I only needed 3), cleaned them out a bit, bumped the RAM and put new disks in them and they’ve been solid.
