I moved and wanted to get a unifi setup, but didn’t want to hide this gorgeous hardware in a closet. So I got an 8u synth rack from ShadyMapleWoodworks. Absolutely love the wood against the aluminum.

It is time for me the replace the aging APC Symmetra UPS I use for my homelab. It is at least 15 years old, and has gone through many battery cycles as well as replacement of all three power modules at least once. It is in a separate room from the server room and is hardwired into a dedicate panel, as well as a dedicated bypass.

My lab is typically in the 4-6kw draw, but sometimes ~8kw on the UPS side. I have it wired with 3x 240v/30amp circuits from the UPS to server room, a couple of 20amp 120v circuits to an AV closet and my office, and the feed into the UPS is a 125amp capable feed. Since I have some 120V loads I need a split-phase capable UPS.

It seems like the logical replacement would be the Eaton 9PX 10kVA. It is online double-conversion, and has good expandability. (https://tripplite.eaton.com/eaton-9px-double-conversion-ups-9kw-208v-6u\~9PX10KSP)

The entire feed into the UPS is further backed up by 42kwh of Enphase batteries, 20kw of Solar, a Generator, and 600amps of regular grid service.

Any other recommendations for something that has online double conversion and enough capacity?

So I realize how much of a newbie question this is but…. I’m a noob 🤷‍♂️.

I came into this Lenovo ThinkCentre M92P with no OS for $12…. Including a mount and power supply 😁.

I would love to make some sort of decent (ish?) NAS server from it…. IF it’s feasible. So my questions…

How would I connect the storage drives…. USB? Bad idea?

Since there’s no OS, I’ve yet to find out what kind of processor it is. Is it possible that I’d have to upgrade the processor?

Should I upgrade the 4GB RAM to more?

I’m sure there’s more to know but honestly I’m not sure if I even know enough to ask the proper questions.

I attached a picture of my current network setup just for fun … Zip ties are bad…. Blah blah blah…I know….

Cheers!

Hello everyone, I am wanting to build my home-lab / server rack / networking rack for my new office and have it like one of those aesthetically pleasing cabinets you see so often here :) However, I am trying to figure out the best way I can run these bulk cables through the wall into the patch panel in a clean manner (Requirement by the wife).

I was thinking of using 1-2 brush wall plates (like these: Link )

with these boxes behind them: Link

So I can connect some sealed conduit to them, with all the conduit running to a pull box (or conduit box) like this: Link

with some input conduits with all cables pulled into the conduit and sealed using conduit putty.

The primary goal is prevent critters from being able to get into the conduit boxes and subsequently into my office as my wife and deathly scared of any and all bugs/spiders/etc.

So the ultimate plan would be the following:

But I wanted to see if anyone else had any ideas or has done something similar in the past?
Thanks in Advanced!!

Finally saying goodbye to my trusty old ReadyNAS 2100 v2 (flashed with OS6) and replacing it with a custom NAS build in the SilverStone CS382. It served me well, but the limitations were showing.

New NAS Specs (CS382 Build): • Case: SilverStone CS382 (8-bay hot swap) • Motherboard: ASUS H110 • CPU: Intel i7-7700 • HBA: LSI 9200-8i in IT Mode • Storage: • 2x 256GB SSDs (1 for OS, 1 for ZFS cache) • 4x 2TB WD Purple Surveillance Drives

Running TrueNAS Scale and planning to expand storage soon with larger drives (likely 8–10TB NAS drives). Eventually I’ll swap in a newer board with dual PCIe slots for 10GbE and future-proofing.

Rack Overview: • Dell OptiPlex 7040 Micro (i7-7700T, 32GB RAM) — Proxmox 1 (self-hosted apps stack)

• Dell OptiPlex 7050 Micro (i7-7700T, 32GB RAM) — *Proxmox 2 (Arr stack in containers) • Dell OptiPlex 7050 Micro (Blue faceplate) (i7-7700T, 2TB SSD) — TrueNAS for lightweight backup of critical data • TP-Link SG1016PE — PoE for security cams + core networking for the house and granny flat • ReadyNAS 2100 v2 — recently retired and replaced by the CS382 build 

Loving the flexibility of Proxmox and ZFS across the board. This has been a huge upgrade for my homelab and a fun build. Pics included for context!

I feel like this just isn't talked about enough so I thought I'd share my experience. For a while now Jellyfin officially supports HW acceleration via RKMPP meaning ARM boards that roughly go for 110€ with 16GB (DDR5) RAM are able to do 4x 4K transcodings & HDR10 tone-mapping (soon with 10.11 even for DoVi P5) while consuming less than 10w! More in the range of 5-7w.
While you can connect your hard-drives via available m.2 ports and a sata card I just have a NFS mount on the board to my NAS via 2.5GbE. This has been running stable and like a dream since the support was added (I've had it running from early adopter builds to now mainline Jellyfin).
Since it uses the video engine as well as the GPU this has minimal strain on the CPU so it can run other software on the side too making it a great homelab docker host.

Do you guys agree that this is an underrated media server / homelab option?

Small description:
Basically a Lenovo Thinkcentr E73

Intel core i7 4770

16GB DDR3 RAM

4x 1TB HDDs, 1 alone for docker, 3 in RAIDz1

PCI 1x to 2 SATA connectors card

Nvidia Tesla M4 (yes, cooled by the fan you see on the side of the PCI cover, converted a fan of a 2005 laptop with 3 pin to 2 pin USB)

PSU (stock, 180W)

SATA Power splitters

256GB Boot SSD (Truenas 25.04)

Too much stuff on docker

P.S. Ignore the fake rat and the state of the last shelf of the "Rack"

The PSU only has very limited output (Dell's [x1 6pin] & [x1 4pin for cpu]).

From this picture, the PSU's 6pin connects to the mobo. The mobo then has an output that connects to 4 drives (idles at ~8W each). I cannot find the motherboard specs but this is a prebuilt Optiplex 3050 SFF. Is this suitable?

I'm waiting for my HBA Card to arrive for the SATA connection.
