ThinkCentre M70q

the N97,N100,N150 processors tend to reach 100% CPU load during mid-heavy task so if you plan to use it for plex only nothing else it should be fine My used Lenovo M70q tiny been runing 24/7 for years now as a plex/jellyfin server just fine can do multiple 1080p streams at once and one 4K at a time

That CPU will be fine but really overkill for what you're looking to do. If you want a really reliable workhorse I'd be looking for a used HP/Dell/Lenovo micro pc with a i5-12500T or better. The UHD 770 will give the same or better performance for plex transcoding and the big 3 have much better qual

All of those models are REALLY old. The Dell OptiPlex 7010, 790, and 9010, are from the early 2010s and are only DDR3. The Precision T5500 is a workstation from the same DDR3 era but only accepts ECC RAM. Workstations typically have different processor, ram and other options compared to consumer dev

I guess it depends on the use case. My kids do game stream (Sunshine/Moonlight) so codec support was important and therefore we went with NUCs (12 Pro I think). For my homelab, I went with two Lenovo M70Q Gen 3. Quiet, small, easy to upgrade and quite thrust worthy brand. Those can be found for €250

Bei mir in einer glasfaser/netzwerktechnik Firma (!) haben wir Lenovo think centre m70q gen4. Die sind gar nicht mal so schlecht. Wir benutzen die um EINE Website darzustellen. Auf die Frage warum kein raspbi: das hat nie funktioniert!
