Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

I hadn't considered that! Thank you.
I'm hoping the OS, as it's designed for this, is going to be helpful in getting the right balance with power usage.
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.
To put this into perspective for you, if your NAS sits at idle for 90% of the time (probably true) and an older CPU is 50w (kinda high, but maybe) and a newer CPU is 15w, over an entire year it will save you around 305.76 kWh. Average price per kWh in the USA is 12.89¢. So over a year a new CPU can reasonably save you around $39.41. So it's not nothing, but it's nothing crazy, but lower idle wattage = lower temp = components last longer, which is the real savings.
If an older CPU is only gonna last you 5 years, when a new might last 10, you're going to save almost $400 in energy and generally a CPU today is going to be cheaper than a CPU in 10 years (probably). So it makes sense to spend an extra $200 on a newer CPU and still net a $200 savings over 10 years vs the older CPU.
This is why I'm using a refurbished mini PC as my home server. Lower wattage for constant uptime at home. Also very quiet.
Bingo! I've got 4 mini-PCs (does a 2014 Mac mini count?), and one SFF. The average power draw of this cluster is barely ~90W.

Yeah with that win10 EOL there's loads of refurbs out there for cheap.
Only one of them is compatible with Windows 11 lmao - HP Elite G4 mini with an i7-8700T. Everything else is 7th gen or 4th gen.
