My old laptop for self hosting just croaked, and I’m thinking of buying a 2nd hand mini pc, but this time I want to do it proper. I want to optimize the electricity consumption and specs needed/ future upgreadability, considering how expensive everything is now.
My use case is just for self hosting files (infrequent access and reducing reliance to google drive), and occasional dev workload via ssh. I’m thinking of buying a used optiplex with at least i6 gen cpu (SFF or micro form factor), but I want to see if there are better options.
There was a link posted in this subreddit about power consumption comparison of different mini pcs (raspberry pi, n100, etc), and I regret not saving it.
If anyone could suggest me better options it would be greatly appreciated. Thanks!

Recently I decommissioned a Dell T320 and replaced it with a Dell Optiplex 7020 SFF with the i7-4790 and 32 GB RAM all for right at the $200 mark. I’m running a total of 52 containers on it right now with load averages looking like 0.31, 0.51, 0.72. The Dell T320 running the same 52 containers cost me $40 USD per month to run. The Dell 7020 costs me $5-8 USD per month to run 24/7. If you wanted a wider tower, I set up a Dell 9020 for a friend of mine’s son who wanted to get into selfhosting at the age of 10. Similar running costs. I’ve got an Optiplex 3020 mini with 16 GB RAM and a 4 TB external drive running Proxmox quite well and costs probably $3 USD per month. I’m pretty well chuffed with the performance so far of the 7020, and in fact am eyeballing another one to replace a second Dell T320.
I honestly need to learn your ways and sell the rack of stuff in my basement. Right now I’ve got an old R720XD with 12 spinning metal drives and 2 SSDs, then another old Intel box the local government used for VOIP (I’ve only got 7 spinng rust and 1 SSD in there), then the R610 that I use for homeassistant and a few VMs…
I’ve also got a smaller desktop for jellyfin/Plex and an old MicroServer (gen8) for a firewall…
I could 100% save some power I just need to learn what I actually need.
Well, it all started way back when, with a misunderstanding in my mind about what a homelab is. Back then, in my mind a server was this big, honkin’, brutal piece of equipment. Over the years I came to realize that all that rack stuff, while cheap upfront on the used market, was costing me some serious bucks in energy consumption + the added load on the AC, even when electricity in my locale is relatively cheap. Since I already was invested, I didn’t want to redo everything and start from scratch. Then the ‘mini-racks’ started to be a thing with Lenovo’s and such. I saw that others were doing what I wanted to do with much less. So, now days, it doesn’t take much of a computer to run docker containers, Proxmox, etc. Far more energy efficient, doesn’t generate so much heat load, and significantly more quiet.
In the near future, my goal is to miniaturize my lab, and then build me a $4k AI machine. Out of the frying pan into the fire yes, but I haven’t had new equipment in well over 15+ years. I’ve always had used or refurb’s. I think it’s about time to treat myself.
Thanks for the encouragement! I bought a couple mini pc’s and one server seems fine going from a lot of memory to just 16GB. Now I guess I need to start parting that one out to pay for a more efficient storage server.
You bet bro. I’m chuffed I could help. I’m glad it’s working out for you. Rock on with yo’ bad self.
