6 servers were decomissioned, Iwas able to only get the disks, RAM, CPUs and Network Card.

The total of this is : 88 x 8TB SAS disks 44 x 16GB RAM sticks (half 2133, half 2400) 6 x v3 Xeon e3 2630 6 x v4 Xeon e5 2640 3 x 10 GB PCIe dual port cards 12 x 1U heatsink

I'm really lucky to have all of these, even if I don't have a use for all of that for now (except some of the disks)

EDIT: Forgot to mention: All of this for free, I work in a datacenter!

I've found the disks hurt my power less than choosing a good motherboard/cpu, and using M2 for the OS drive.

Using it drives up power. At idle, my latest 5-drive setup draws 20 watts, it goes up when I'm copying files to it (usually syncing media files from 2 other local storages).

Compared to my old system which was an ancient gaming rig that drew 120w at idle, with only 2 drives (OS and storage).

I also have a 5 disk NAS running some old drives, it's idle power is so low I've forgotten - maybe 15w? The most it could potentially draw is about 60w, since that's the power supply max - I've seen it draw 45w while rebuilding a disk.

That's super low. What drives do you have? Are your drives spinning down?

It's a mix of crap I've acquired over the years, all 1TB drives, 3.5",most 5-10 years old, in an old Drobo I inherited. Yea, it's a massive risk, but it's one of 3 storage systems replicating data locally, plus a Crashplan backup.

Since it's 5 drives, I'm pretty sure it spins them down - at best if they drew 3w each, it'd be 15w in drives alone.

Running it on a smart switch, I've never seen it draw more than 30w, and that's at boot time with 5 drives.

My 3-drive Proxmox box (a Dell SFF) drives are a mix of spinning metal and SSD (2.5"), it idles about 20w, peaks at 100w when I'm converting video files with a VM. That hardware is about 5 years old too, 32gb of ram, booting from an M2 drive.

My use-case is very high idle time (95%+?), so I'm targeting lowest idle power consumption. Pretty much anything will suck power once I'm doing anything heavy (like video conversion).
