New server for home

When I look at my electricity consumption, I realize that I do need to lose a bit of weight. Yes, I could lose a few kilos personally, but especially when it comes to technology. At the moment, what’s going on in the basement is perhaps just a bit excessive.

So, the current situation:

HP DL360 Gen 9 with 1x Xeon, 128 GB ECC RAM, 8x 1.92 TB SAS SSD and an idle power consumption of around 100 watts.
It currently runs Hyper-V with VMs for file servers, Jellyfin Mediacenter, Adguard Home DNS Adblocker, qBittorrent and some other unimportant stuff.

Since the network infrastructure here consists of 1 Gbit/s LAN or WLAN, a server with all-flash is nice but pointless and the power consumption is more of a problem. In addition, the usable capacity in RAID5 is unfortunately a bit limited.

Requirements:

A new device should consume significantly less power.
A file server that speaks SMB is a requirement.
Jellyfin is set, under which operating system does not matter.
Adguard Home also needs to be installed again, as well as any download client.
The new hardware shouldn’t cost a fortune.
4x 8 TB NAS HDDs would still be left, 2x 256 GB NVMe SSDs would be at hand and at least the HDDs should be used.

I’ve already looked a little into NAS. Ugreen DXP4800 or Terramaster F4-424 would be candidates, but not the Pro or Plus version. In the future, 2.5 Gbit/s LAN may be available, but 10 Gbit/s will not be reached.

You could then install a TrueNAS Scale on the NVMe SSDs. This would make you independent of the respective software from the respective manufacturer. The desired software would run on each container. Or would you rather use the manufacturer’s OS?

Or would you rather spend a little more and get a QNAP TS-464 or something similar?
I assume that building it yourself is not really an option. You can’t really do it in a way that saves energy, can you?

Maybe someone has some ideas. If you need more information, just ask!

Thank you, Ingo
