Idk if this will help, but there are plenty of SFF systems on eBay, but I’d just be careful about what you want… I thought those looked good and bought a Lenovo but then wanted 10Gb Ethernet for a NAS and now I’m putting together a 2U rack server! Not to say you’ll do the 180 I did, but just keep future expansion in mind…
Hey of course, sorry for the delay, work has been crazy! I put this together from eBay and Newegg, I’ve installed UnRAID and am trying to get everything setup, moving Dockers from the tiny Lenovo to this, and replacing my Synology DS920+ eventually. The UnRAID forums are extremely helpful!
