Nobody is using MMF these days even for local runs. As to sfp, check https://fs.com and pick a matching pair that is cheapest. These days it makes sense to use 10G or 25G rather than 1G. Some people run 100G for their homelab, but even used it’s pricy and noisy.

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.

Interesting, wasn’t aware. It remains illegal in Germany then, as long as you seed. Notice in Germany you will receive a nastygram in any case as long as you’ve been identified as a member in a swarm, even if you do not seed. It would be interesting if someone would contest that, though you will likely lose since technical details don’t matter in most courts.

No port mapping, no upload, so technically legal where only sharing is penalized. IANAL.

Since most VPNs no longer have port mapping it’s a pure download which would make it technically legal e.g. in Germany.

Without VPN or Usenet subscription it’s going to be difficult and/or illegal.

An L3 switch is a router. Though most of them don’t have enough resources to take a full BGP routing table, at wire speed.

Long term storage requires an ongoing migration strategy. The whole ecosystem for reproduction gone away your pristine media will be inaccessible.

What’s a reddit?

Linux and a bunch of ebooks. Maybe Larn and Nethack.

Also opnsense, but on thin client.

Why not postfix?

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.

Proxmox with Debian containers.

Did you get it used? For how much? How is the noise level?

Read that as religion blocked printers. Ought to delete that, don’t want to give them ideas.

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.
