Hi, i currently renting a server as Hetzner for about 90-100 euro/month

I was thinking that it might be cheaper (per year) buying my own server for like 1-3k euros and go to a co-location with the server and "only" pay for the electricity, hosting and internet, and not continuye pay for the hardware it self.

But every time i try to "pick together" "my server", it becomes really expensive because i want to add "this and that" and have "more power than the universe" in my cpu.. (which i probably dont need half of it)

​

I currently got something like 20TB harddrives (summed up), 128 GB of ram.

I would need atleast 10TB storage.. perhaps even closer to 100 GB for offsite (off-home backup) Need some space to test virtual machines of what ever i want to test/do today.

Currently i only run 3 servers that is java based, semi-moderate cpu usage, moderate to high storage usage both in space and "traffic". No time sensetive that needs to happen i real-time.

​

Any idea of what kind of hardware i should look at, limit to how powerfull cpu do i really need and stuff like this.

128GB of ram, is nice to have.. but i dont think i need more than 32-64GB ram for my current usage.

And hardware/storage.. it becomes quite expensive if you skip the consumer level stuff.

​

My initial idea getting this server was to host my own mail server for my 3-5 domains. Host my business low-trafic webpage (almost no trafic to the site, almost no content so basically more or less a static page or three). VM's to test/seperate other stuff that i either need or want to test/do.

I often look at bargainhardware.co.uk for refurb server and hardware, and even here (post-brexit) the server gets really expensive.
