It is a meme post?
It's an enterprise server, with dual sockets, a lot of cores and ram. Not built with power saving in mind. And not built to be used on a home.
Have you done any research before buying it? Probably no.
That is normal power consumption behavior. And you are lucky that it consumes not that much for what it has.
That's a good way to kill a disk. Don't use NTFS and you are fine. Go for Btrfs and similar.
Do you really need 42U? Can you sell it and get a smaller one?
However, humidity is a big problem.
Old Hardware, and very power hungry.
Look for desktop systems from main brands like Lenovo, Dell and HP, go for a G5400 or i3 8100 with 16gb of ram. Those are generally limited on hdd space, so if you need more than 2/3 HDDs, it would be better going DIY.
If you need a lot of VMs, going with an i5 is fine, better a normal one, avoid the F.
Just to say, NAS and docker (even 100), work easy on a dual core or quad core CPU, more is just for the VMs.
I would avoid the Gaming VM and get a Gaming PC. For obvious reason, compatibility, latency, anti-piracy software like Denuvo etc normally don't like VM etc.
Instead of 4 3TB drives, i would get a single 12TB drive, maybe 2 for parity.
The PSU is overkill, get a 300/400W one.
No need for the GPU, HW transcoding work a ton better with the integrated iGPU, using an external one would be a massive downgrade, of course you need a normal CPU, avoid the F one.
For the sata card, i think an HBA would be better, but i'm not an expert on that.
For Retro stuff, is very good. Like tinkering with old OS, old standard etc.
If only something like a search engine, existed, I could search for a manual. Fuck. What a life.
UDIMM DDR4 2133mhz, memory module from 4,8 and 16GB. Max 64GB. It can support ECC.
Ah, UDIMM is unbuffered DIMM.
Stick with the 16Gb you already have and it's fine.
Your electricity company loves you.
With xeon it is a bit more difficult to have lower power consumption, they aren't made with power consumption in mind but performance 24/7. But 30/40W I think it's likely possible. L variant can idle a bit lower but not as good as desktop CPU.
The problem with gaming PCs is that generally they have a lot of RGB, fans and VRM, mine too idle around 80W, even if I tweak it very well, and fun fact I can lower my 9900k to 6W and my 2080 is around 12W, but I've 6 fans, RGB on the motherboard and ram, I've 32gb of ram too, and my motherboard have tons of VRM for good OC. Not only, I've a 850W PSU so the efficiency curve is around 450W, at 60W load the PSU takes 80W from the grid, and generally efficiency is around 80%.
Going for an OS without a UI, no monitor mouse and keyboard. All HDDs idling, I would say less than 20W.
HDDs generally idle at 0,3W, spinning and writing/reading around 6W and from idle to spinning around 12W for a peak.
Very plastic, i would prefer a R6/R7. But nice!
You need to be deaf to not hear an HDD, and Helium one are generally very noisy.
