You can calculate it !
Take your power usage and compute the cost over a year.
I will soon add a SSD because i finally moved from a RAID 1 to RAID 5 (so more HDDs), it consume more electricity.
I can measure how much power it draw because the server is on a smart plug. I calculated an additional 20-30€ a year of electricity, adding a SSD for read/write cache would allow the HDDs to stop spinning, make things faster and will be cost effective over a few years.

Consider that a new power efficient CPU may be cheaper by consuming less electricity over a few years!

Got acquired and rised price.

If only it didn’t looked like a 20 year old software.

When you are bored, backup a VM then hard kill it and see if it manage to restart properly.
Software should be able to recover from that.
If it doesn’t, troubleshoot.

Reading the title without seeing the category name …

Where I live, for 45€ you get 800GB, not 8TB :').

They want you to install their client, but it’s wireguard under the hood, so you can make it work with glutun.
You need to generate a wireguard config file with this tool: https://github.com/ViRb3/wgcf
There is a bug with gluten which make it not accept nameservers for a custom wireguard config: https://github.com/qdm12/gluetun/issues/2042
So you will need to resolve the IP yourself.
Personally, I set it up through TrueNAS, and I didn’t managed to make it work with a file config, so I passed everything through environment variables.
Use this wiki if you are lost: https://github.com/qdm12/gluetun-wiki/blob/main/setup/providers/custom.md#wireguard
It output in USA for me, it torrent with a very decent speed, 150-200/Mbps.
And yes, it’s free.

Cloudflare warp VPN does that.

You just made a mistake into saying what domain name you will take, someone may buy it before you in order to extort money from you.
It probably won’t happen but…

It’s a few euro per year, plus you can mutualize the cost with your family, take a domain name with your last name, this will allow your whole family to have firstname@lastname.yourcountrytld.
I just looked for my lastname, it’s around $10 per year.
I’ll repeat this again, but it means you will own this domain name, you have legal ressources and big companies won’t be able to take your mail address from you.
Else, use duckdns if you really don’t want to pay anything.

I don’t know, maybe ?
But I recommand strongly to have your own domain name.
As long as you do nothing illegal, when you own a domain name, you have legal recourse to keep it. It’s not the case for an email service mail like gmail, which can ban you for no reason tomorrow, and you have no recourse to get back your email address back.

I recommend duckdns instead, which is more well known in the DIY community. It’s also a dyndns like other told you to use.

The thermal dissipation is directly linked to the amount of power consumed.

I just bought a cheap Intel i3 10100T that have a TDP of 35W.
There is a bios option to reduce that to 25W.
Thoses are not sold to end users and must be purchased through craiglist or equivalent.

It’s MSI, not surprising.

Without even opening I had this in mind.
