Another used Xeon option you might consider is refurbished Dell and HP workstations. One that I like is here where you can custom configure a Z440 workstation with (for example) a 14 core E5-2690 v4 processor (AVX2) with 64 GB ECC RAM, 500GB HDD and 700W PS for about $600. The system is built, tested, and shipped free with 90 day warranty. Basically they save you the time, risk and possible frustration of integrating a bunch of parts yourself, for a small fee. Credit goes to Xyzzy's YOLO thread for pointing out these types of systems.

I know having actual kit to play with is fun. But, at least personally, when taking cycle-per-dollar into the calculus, Cloud is the only way to fly. We do pay stupid coin for both CapEx and Electrons here, though, so others may have different metrics. |

Around here each baseboard consumes multiple kW’s and a good proportion of the heat is lost heating the windows and walls. I would argue that any middle of the room heawould actually save electricity. There is new trend here where Data centers are built in church basements providing free (to the church) heating.
FTR, I believe my electricity consumption has gone down since I have started using electric space heaters and heat-dishes (without changing the baseboard thermostat settings). Last fiddled with by a1call on 2022-01-09 at 22:40 |

Our problem here is always moving heat out of one or more (relatively) closed systems. And, personally, I don't believe in cooling Humans using electrons (beyond fans). Only machines; and only then when appropriate. |

When looking at actual mini-PCs (most of which use soldered laptop CPU's and coolers integrated into the chassis to fit the form factor of ~120mmx120mmx50mm), it's hard to beat something based around Zen2/Zen3 which can have 8 AVX2 cores. Energy efficiency comparable to GPU's (just at much lower throughput), space efficiency is good compared to desktop/server CPU builds, but it's probably not price-efficient to rack them up (under normal circumstances, no idea about pricing or availability of anything nowadays).

I'm surprised not to find much (any?) mention on these forums yet of the 1L class corporate desktop PCs, or as ServeTheHome (STH) has coined the term TinyMiniMicro PCs.
STH content on the subject: https://www.servethehome.com/tag/tinyminimicro/ STH forum discussions and references: https://forums.servethehome.com/inde...riences.30230/ In summary:
For under US$1K, it should be possible to get 16 cores worth of Skylake (or newer) i5, and maybe some extra RAM to run dual channel. |

Right now I'd build around a i3-10100 or i3-10105, F or non-F, two sticks of DDR4-2666+ (dual rank if possible, though that's tough to find in the least expensive kits now), the cheapest motherboard, and a gold or better PSU. You can run 4 of those CPUs off a single decent PSU as long as it has two 4 pin CPU connectors (using a 3 2-way splitter off a single 4 pin got too warm for my liking). |

If you are using the small PC's for heat, I would suggest that where you can, you orient the fans to blow vertically (to mix the room air.) And if you have more than 1 in a room, placing them in a chimney of some sort (instead of a case) with the MB and cards in a vertical orientation and using the harvested case fans to move the air up the chimney. A creative person could make the shaft as part of a book shelf or cabinet.
