I'm looking at throwing a TinyMiniMicro style box in a location where performance isn't key, but size is restricted to a micro size box that will sit on a 1U shelf (needs to be self contained, on external HDDs, and will be with other devices). Idle/overall power needs to be as low as possible (so, looking for i3 or even Celeron class processing power).
The use case will be as a super dense storage node, however storage redundancy isn't important. I've looked at ARM based SBCs, but these are all too janky to be reliable.
I have 4x 2TB M.2 NVMe SSDs and an 8TB SATA SSD at my disposal.
The Optiplex 7080 Micro looks like I can squeeze 2x M.2 SSDs in it along with 1x 2.5" SATA SSD. It might even be possible to squeeze a third M.2 SSD in via the WiFi slot with an adapter.
Can anyone think of any better TMM model? Bonus points if you know of anything lower power (I'll be paying for electricity consumption, and the rate is very expensive).
[edit] Size clarification.
