If you don't have enough sata ports on the mobo (the optiplex 7010 has 1x Sata), you'll need a pci sata controller, is my understanding. Not sure what other possibilities there are to connect more hdds...

As this is self-hosted, I feel the majority will reccommend against a Synology or similar pre-built, closed source solution.
At a budget of 150€ it will probably be challenging to build a whole system with new parts, but it can certainly be achieved with two or three generations old, second hand hardware.
The easiest way would probably be to keep a lookout for old office midi-towers (Dell Optiplexes and similar). Those usually have a few pci slots to throw an hba into and hook up a few hard drives. The mounting of the harddrives itself will need to be handled with uhm... Creative solutions. Depending on the system, you'll probably want to upgrade the ram. And if you want easier Hardware handling, you may be able to just throw the system in a different case later on.
Another solution, and maybe even cheaper would be an old NUC or other mini-PCs. To be honest, I have no idea how people manage to use those as NAS or how you are supposed to manage multiple hard drives with them. External enclosures? Then there's also more Pis and other micro PCs. Same challenges.
So, this writeup has not actually adressed your question: what's the /best/ solution?
I also have no idea. It really depends on what you want, what your budget is, how much you want to fidget around. How much space do you have to put a system? What is on offer around you? Does the company/university/school you work at maybe offer hardware they would otherwise need to dispose of? Check craigslist/marketplaces/ebay.
I am partial to the midi tower approach, as it offers a good deal of flexibility, depending on the included motherboard.
Hope I could offer at least some help :)

//Edith: The least energy consumption would probably be the Pi, but depending on how much HDDs you add, this will also depend on what management System you run and what HDDs you use (some NAS drives come with some powersaving features). If you are in any position to do so, talk to your landlord or Eigentümergemeinschaft and get a Balkonkraftwerk. Those 800Watts will more than offset your Homelab needs.

That's not the case everywhere. This is not an individual problem in some countries, it is systemic. That sometimes includes the US. Even Europe has countries with undrinkable tap water.

Howdy. I have a "homeserver" that I'd like to actually start using. What's currently keeping me from it are... Permissions.
I have TrueNas Scale running on top of Proxmox, and I can't for the life of me not access NFS Shares from other VMs (specifically a Debian VM that I use as Docker Host) that I host in Proxmox. Plox hlp.

Thanks for the additonal link. It's interesting that Signal didn't provide the last time the user connected to Signal here, as that was information which was requested and information that they have...

There's other ways to donate to Signal, including crypto listed on their website.

That is not what I'm trying, no. Sorry if it came across like that.
My point is, that this isn't an effective proof of a zero knowledge approach. In their blogpost, Signal says they don't store anything, but this specific instance of a search warrant doesn't serve to prove that.
It is great of them that they publish when and what they are asked to disclose, that practice is definitly appreciated. I do trust Signal, it is my main messenger.
This is just not the stresstest @Fuzzy_Red_Panda@lemm.ee makes it out to be in the top comment, imo.

Well, i'm not fluent in legalese, but isn't the search order also exclusively asking for those two datapoints and nothing more? They're not asking for message timestamps e.g. or other metadata.

I switched to Aegis

Eh, that's what they called it in the article and I'm neither a physicist nor a material scientist. They made a definite distinction between the two forms of the materials in this and other articles related to the topic which I was too topic-uninformed to understand. So you might be right :D

Afaik they just discovered that Ice has a layer of water ("pre-melted ice) at the surface, which is the lubricant that makes ice slippery. So, imo ice is wet ^^
