Probably the Odyssey Blue, which uses a Celeron rather than an Atom CPU. I disabled the fan so it is silent, and the temperature stays very stable (and pretty low). It’s a wonderful device. I’ve programmed the Arduino and use it with Home Assistant (serial sensor). My Odyssey Blue is virtualised using Proxmox and also runs OpenWrt (router), Home Assistant, UniFi Controller, Plex, Transmission, CUPS, SAMBA and more. It still has plenty and ram and CPU left too, if I only I could think of anything else I want to run on it.
This isn't very helpful as Intel calls some mainstream core based processors Celerons, and some atom core based processors Celerons.
The current trick is J before the four digit number is Atom based, U after the four digit number is mainstream laptop core. G before gives you mainstream desktop core for Pentium, and I think Celeron as well. But really just put the model number into search, go to the Ark page and see that it's products formerly Blah and then look up Blah to see what that actually means. Yay marketing.
Yeah, that's definitely an Atom (or Intel is calling them low power cores now). It's fine, you're clearly happy with the product and Atoms are generally ok (other than some issues with Bay Trail that resulted in an early end of service in early steppings), but the cores are roughly 50% the performance of contemperaneous mainstream cores, and it's often not totally clear when comparing a Celeron to another Celeron that one has half as powerful cores.
