If you pay a lot for electricity, you could get heat cheaper with a heat pump, gas furnace, or simply adding insulation on the roof/walls so any heat you do add lasts longer.

Re-insulating a house is a substantial cost that can take a decade to pay back in utility bills.

Yet spending $6 on draught excluders to keep the wind out can pay back in just a day or two.

It all depends on your baseline...

I’d strongly recommend people take a look at the supermicro (or your vendor of choice) Xeon-d or AMD embedded 3000 series.

Lower power draw, very quiet and more than powerful enough to push 25gbit with cpu left over for VMs.

"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…

That‘s a switch, not a router. Much simpler hardware.

Here‘s a MikroTik Router with 28 Gbit/a throughput: https://mikrotik.com/product/CCR1036-8G-2SplusEM

$1300 and up to 73W

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…

I have decade old hardware that is certainly inefficient, but my services hosted have taught me so much it's not even worth the comparison. Yes, electricity is cheap in America but we all choose to spend money on our hobbies as we please.

I'll bet there's a few nitpicks with your hobbies where you trade a lot of time/money/something that I don't necessarily understand. And that's okay.

This is a switch and switching is hardware accelerated. While you can theoretically route with this this, it is incapable of routing at gigabit speeds, let alone 10 gigabit speeds, once you need even a few rules.

That's a bit of an odd example to choose.

This[0] has a $600 MSRP, with twelve 10Gbps ports and two 25Gbps ports. It's ~32W before you add the SFP+ modules, and upwards of 50W if you have all modules populated.

In the benchmarks they list, this can provide somewhere on the order of 13Gbps to 40Gbps of routing, depending on exactly what you're doing. (Smaller packets will lower these numbers, but if you care about bandwidth you're unlikely to be worried about smaller packets... at that point, you probably care more about kpps.)

I have 10G in Tokyo and I think it’s about $60 USD per month vs $40 for 2G. It’s definitely overkill but it sure is nice to download a 60GB steam game in a minute or two.

The problem with 10g is that most servers aren’t on 10g yet and if you’re transiting a peering connection of a smaller ASN at some point, even that is likely not 10g

Agreed, I struggle to get anywhere close to 1gbit/sec apart from Steam.

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 for my family, it would be a total PITA to manage, and any downtime would be horrible.

So, stuck with UDMP for the moment, until they either fix their problems, or alternatively I decide to bite the bullet and build this on top of linux.
