We were at 5MWh last month, so it’s all relative. Don’t feel bad.

That is impressive! Did you do that on a 200A 120/240V service? What is your load? Ac?

Not the person you were replying to, but my June statement lists 1,800 kWh. I'm in a two-bedroom apartment in Texas. The primary consumer of power by far is AC, which is kept at 68 degrees in the summer (partly for temperature, partly for humidity). My effective rate after all the fees was $0.11/kWh.

I have a Unifi UDMP, which while I think is probably the best prosumer option right now, falls way short due to a PPPoE problem that limits fiber connections to under 500mb/s, and the lack of load balancing across multiple link networks (which I totally admit, is a first world problem). I am thinking about building my own, but then comes the maintaince of all of the hardware / software. For me that would be fine, but…

how are you achieving load balancing? using LACP? not having working LACP seems kind of unacceptable in my opinion for suchs an expensive device.

Also, older enterprise grade routing hardware can be had for very cheap.

At work people leave their computers and screens on (and unlocked most of the time)... (edit): I tried to educate but nobody really care...

Maybe in your office, but when I was in the office we had a culture of pressing Win+L or the dedicated lock key on the keyboard and letting Windows turn off the display after a minute of being on the lock screen.

That's what Group Policy is for.

My home server is about 70W, meaning about 150€ a year (~0.20 eur/kWH). So about 12€ a month. For one of my biggest hobbies. It’s fun, but it also runs WireGuard, 3 NextCloud installs, Home Assistant and Mosquitto, 2 MineCraft servers, a FoundryVTT instance, samba, sabnzbd, Unify Controller, an Nginx static site, LibreSpeed, VaultWarden and soon a Django site. Oh and a virtual desktop (vnc) I can always leave running…

> (~0.20 eur/kWH) Are such high electricity prices common in Europe? That's higher than it is in 49 of the 50 US states (assuming 0.20 EUR = 0.24 USD, and with Hawaii being the exception).

I assume it varies a lot by region. 0.12 EUR/kWh for me (Finland, inc. transmission and tax).

I'm always amazed by people who don't bat an eye on the perspective of having a home server, sucking up electricity 24/7. In this case replacing a typical router (which consumes like a lightbulb), with a full-fledged PC (probably consuming like x100 the power). I guess some people around the world have quite cheap utility bills! For me, it's either a Raspberry Pi type of power consumption, or else a server that only…

There is such a thing as wake-on-lan

"probably consuming like x100 the power" is greatly exaggerated. A typical PC might have an idle power consumption of less than 50 W, while a very small computer with ARM little cores might have an idle power of 2 ... 3 W, so at most the power consumption ratio would be 20. However even that is not realistic because a computer or appliance with less than 3 W power consumption will not be able to route 10 Gb/s or fast…

SFP requires less energy than RJ45, only 0.7W/port. The MikroTik 4-port CRS305-1G-4S+IN draws 10-18W.

> MikroTik 4-port CRS305-1G-4S+IN

I have two of these at home, they're neat little bits of kit.

They're fanless and therefore silent, which is fine until you realise you want to do 10GbE over existing copper cables with something like Mikrotik's S+RJ10 adapter. Then the temps start to rise...

So, I've decided to go completely to fibre, even if it means opening up the walls of the house. Just bought a job lot of used ConnectX-3 cards off ebay.

Can you still find "desktop" motherboards to go with them? A long time ago, I remember there being desktop MBs for the Pentium M.

For an always running thing, choosing a laptop motherboard is a nice way to guarantee all the power saving features will work properly. Most desktop motherboards won't allow the PCI express bus to sleep for example, using an extra ~4 watts, $8 per year in eco-friendly countries. Across the ~10 years your NAS will probably sit in a cupboard, that's $80, which isn't an awful lot, but probably would have let you buy a b…

That's true, but then again I wouldn't be comfortable with a single-disk NAS...

However, for running random VMs, etc, I think a laptop is quite a good proposition.

Good post, bring me back old memories where I used to setup my own PCs back in high school. I think the graphics card and GPU are really not required for a router. Few years ago there was a Linux project called zebra router which was deprecated in favor of https://www.quagga.net/

The real story here is how great the internet service can be now in a civilized country if you don't let Comcast have monopolies and ban local internet cooperatives and coast along selling the same service for 15 years while raising prices.

25Gbps symmetric for about $70/month. That's significantly less than I pay Comcast for its crappy 900Mbps down/40Mbps up service.
