Question Best bang for the buck home server


Hi
Not sure if i'm putting the question on the correct forum section but here it goes:
I need to put an in-house solution for my database main server. I'm paing a ton of cash to have this server in a datacenter and i don't need it there anymore, i need it in my house.
It is a database server with 32 cores 128GB of ram and costs me almost 300€ per month.
I have a NAS with backups and i can have it at home and the specs i wanted would be
128GB ram
32 to 40 Core cpu
all SSD raid 10, from 6 to 8 hard drives or 7 ssds and a 12tb normal drive for local backups + an NAS i have on another location for backups too.
I was looking on ebay for an used HP z820 since it is an almost silent super powerfull workstation and some have 40 cores, 128gb ram, and so on. Looks like it has some kind of watercooling to keep the noise down and i saw prices going from 750€ to 2k depending on how much ram they get, or the graphics card wich i dont need.

For a "cheap" low-noise solution for my home is this a good machine? any other suggestions? i looked into a more modern threadripper solution but the cpu alone cots more than this entire solution.

Btw just to keep this out of the way right away, the energy is not an issue, nor the connection.
Thanks in advance

Without knowing any load metrics I don't believe I could guess.

I see web sites where they post scores for products from kernel level to filesystem to simulated loads for almost any common hardware, processor.

The web sites like HP offer clues sometimes to the types of servers that can be used.

Knowing your resource hungry applications would be a must.

um.
these are your requirements, for a purely local home server?
may i enquire what you think you need all that horsepower for?

I have a Z420, not quite your spec though, no water-cooling, and much cheaper (but rock-solid, looks like new inside and outside, lovely box). It runs Windows rather silently, but I have not found out how to convince Linux to better manage the CPU fans. In short, not THAT low-noise with Linux. But perhaps the solution is there and I am too dense to find it.

Hi ondoho, of course i can explain.
Me and some clients of mine have a big email central server with every one's databases inside, similar to sparkpost but it's our own solution.It is a server with lots of databases and it is on ovh and is super expensive.
It needs ssd's for super fast database updates and when not on load of course it's idling, under load when everyone is sending campaigns and stats are updating, cronjobs running and all of that it fully uses most of the 32 cores it has. At the moment its curious but the bottleneck is the cpu and the database system. It is a fully optimized mariadb database (For the hardware we have at the moment).
At home i have 2 servers and ups's like a mini datacenter i built, i have almost no downtime and these 2 servers could be turned off if i built a bigger server and virtualized these 2 as vps's and putting like 95% of the resources on the big one.

By the way, before anyone asks, yes i have a good uptime, i have 2 fiber connections at home, one of 1000/500mbps and the other one has 200/20mbps. i can put the server using any of them, we made calculations and the upload is not a problem at all, also, email tracking, dns and all of that is done on a cheap server so that we have virtually 100% uptime, even if my home pc is off for 3 days we dont lose email tracking, opens and clicks, in the future the central stats vps will probably be a cloud solution on amazon or something similar instead of a cheap server that can fail.
So this big server that costs us a ton of cash basicly just has the email platform that is not public in any way, only direct access users can use it, and i can have it on my side, make backups and all of those advantagens, and by my calculations it could only cost like 25 to 45€ a month on electricity instead of paying more than 300€ a month to ovh. Also the 2 biggest clients also are willing to support the built or pay for the electricity costs instead of the ammount they spend right now.

Yes berndbausch i also thought of instead of buying the hardware, i saw the HP z820 but im not sure... i have the money on the table and so many doubts

ok, so it seems i misinterpreted the term "home server". or you misused it, whatever, probably not a precise term in any case.

Problem solved. Bought a dual xeon 40 core 128gb lenovo c30 from a friend of a friend for 800€. Not those many sata ports but for now it works.
