I would look into thin clients and Lenovo etc. tiny PC for office on eBay. I run old low power low noise rackmount Supermicros which are nice but hard to find at low prices.

Factor in power bills and heat and noise into your calculations.

Also opnsense, but on thin client.

I hear you, but Proxmox does a great many more things than just run containers. Admittedly, many selfhosters won’t need these.

It’s a NUC so sufficiently poweful. Proxmox isn’t fat by any means. If you run your stuff in containers then Proxmox (I aways install it on top of Debian) is your hypervisor is your base system. You typically don’t install stuff on your hypervisor, though I do some very select things.

You’re probably drawing about 400-450 W.

My current supplier rate is about 0.6 EUR/kWh. I make some 1/2 to 2/3 of my power myself, for a price that’s less than half of that.

How many W are you pulling, on the average? Or kWh per year.

My primary consideration is all the expensive storage filled up by vapid image macros. 80 GB goes a long way for just text.

Pictrs should have been an optional microservice by default. Commenting here to keep track of this thread since this is useful.

I’m only missing a hole in the wall to do the same – and I could be running a 2x 40G link!

But the switch idles at 80 W and a starting jet noise level, so the hole in the wall will wait.

YaCy indexes http content, so if your documents are all reachable via a http interface they can be indexed.

I pay 0.7 EUR/kWh though it’s capped at 0.4 EUR/kWh at the moment. Which is why I make net half of my power myself. At some 1 EUR/Wp it pays off really quickly.

About 70 W for opnsense on a thin client, an Atom Proxmox and fanless 24 port switch. North of 6 kW if I fire up everything.

You might want to look into all-in-one zfs, which exports your pool as an NFS share internally and externally. In case you use spinning rust, L2ARC and ZIL are your friends.

Do you trust yourself to sustain this considerable commitment?
