This is my Home Office lab where I remotely work you can say WFH.

Hey everyone! Here's an update on my home lab, which I've been working on for about three years now. The entire setup is mounted on a 42U open server rack. Here are all the details:

Power Delivery

At the very bottom, I am using a 900VA inverter with a 200Ah battery, running in UPS mode, which provides safety and power backup to everything on the rack.

The inverter output powers a single power strip located just above the inverter, and this same power strip powers the other three power strips at the top. The three servers that you see just above the inverter are powered by this same strip, while the topmost power strip powers the remaining things, which I will elaborate on further.

I have downsized my rack significantly. Before I had a mini K3S cluster of eight mini PCs, hence the two extra power strips, although I am not currently using them for anything. The plan is to rebuild my K3S cluster and deploy again.

Networking

The current local network is powered by a 24-port gigabit switch from TP-Link (TL-SG3428), which connects everything through a 24-port patch panel.

Router is a mini pc with 4 LAN ports (G1 Thin Client - Intel J4125) running OPNsense with dual 100mb/s internet connection with static IPs set up to failover automatically.

Additionally, got four gigabit access points covering every nook and corner of the home.

Servers

The one at the top is my bare metal TrueNAS server. It's a 6-core, 12-thread system with 64 GB of DDR4 RAM with two Seagate IronWolf 16TB Enterprise NAS Drives in a Mirror. It's running a few services like Jellyfin, Immich, QBitTorrent, etc.

The one in the middle is another. It's a 6-core, 12-thread system with 64 GB of DDR4 RAM running Ubuntu Server. This used to run a lot of production code for my business, but currently it's sitting idle.

The one at the very bottom is a 4-core system with 8 GB of DDR4 RAM, which used to run my OPNsense before I moved it to that mini-PC. The goal is to replace the internals with either a Ryzen 9 5950X system, which I currently use for Proxmox, or a Ryzen 5 5600G system that is currently idling, waiting to be deployed for experimenting with random services and learning.

There's also an RPI4 next to the mini-PC running OPNsense. It's pretty much used to host a few Discord bots, Nginx Proxy-Manager and personal projects.

After a few months of lurking, today is Time to Show off:) I discovered this sub when I was in Hospital a few months ago. I ordered some stuff and began to tinker around. I Thought about buying a rack the last few days. Today I decided to Safe a lot of money and make a rack by myself. It was only 14€ for 2 wood planks.

Running true nas on the m700 with jellyfin and a minecraft server. But I will start over with this one and go with ubuntu server too i guess. I want to try to get used to Containers.

The m710q joined last week. It is Running ubuntu Server. I will use it for a fotobooth project. The fotobooth will send the Fotos straight to the m710q and Clients can Download them from here.

Playing around with tailscale to manage the fotobooth from Home if it is at a Client side.

What do you guys think?

So right now from my ISP I have fiber optic running into a optic transfer box then the run cat5 cable to the our router. Now the Question is would a managed network switch do What the optic transfer box does or am I crazy?

I’ve just finished adding a couple more servers to my home lab so I thought I would upload a pic onto this sub edit to get a couple people‘s opinion on it so far it’s a couple hundred terabytes so it’s nothing too insane

Got all 7 servers for $500, not the most efficient or new but they should still perform well (Yes I know the servers need cleaned just waiting to get a door filter)

Specs: 1 dl360p Gen 8 64 Gb ram 2x Xeon e5 2640 6C/ Thread

1 dl380p Gen 8 128 Gb ram 2x Xeon e5 2620 6C/12 Thread

4 slot GPU makes impossible to get any other additional cards so I needed to improvise it. I have 5070ti at the top slot. Intel x540-t2 nic at the bottom one and riser cable from the middle x4 pcie to connect LSI raid card.

Got a wild hare and decided to design a cabinet for equipment that should be nearly silent. I took inspiration from subwoofer boxes and their ports. In their case, the porting allows even more low-end noise out of the box. In this case, the "airflow duct," as I will call it, will be lined with closed-cell acoustic foam. The entire enclosure will also be lined with this too. All joints will be filled with acoustic caulk, and a gasket/foam rim will be used around the front and rear doors. The doors will use draw latches for a tight seal. As it stands, it's around 5ft tall, 20U's, and 45in deep(overall). The fans used will be Noctua NF-A12x25 PWM fans going to a PWM controller and (haven't thought this far) either a knob on the cabinet itself or to a networked controller.

Will be made probably out of MDF. The posts holding the 20U rack ears will be 2x4's. I may upgrade the bottom panel to be plywood to take on the weight, but not sure on that yet. Was considering a plexiglass insert in the front door, but tour the most sound suppression it may not be best. Blanking plates will be used.

Let me know what y'all think, or if this is overkill for sound dampening, or if you don't think it will work at all, or things that I could add to make it better! Yes, this is in projects because I intend to build this, unless you convince me otherwise.

Hi all!

I posted here a couple of months ago with a Dell Optiplex 3050 Micro I was planning to turn into a Jellyfin server by heavily leveraging Gemini (I haven't coded since A-Level).

Well, I've been ill and I decided I needed a project to keep me sane so I thought I might as well take a run at it, and I'm happy to say that it's working great!

Tdarr isn't working properly yet, and I almost lost my entire library moving to an OS RAID array made up of the hard drives in the DAS (before I had Duplicati, had to recover from metadata that wasn't deleted), but it's pretty close to complete in terms of the media server.

Currently its built as a group of dockerised modules, one for central services, one for the media server, one for an ebook server, and one for a Minecraft server. Its designed to be flexible and in such a way as I can bring down modules for maintenance without having to bring the whole system down or faff about with individual containers. It also has a docker network to allow all the modules to communicate, and I've been using Tailscale for access (although I have a web address and will be trying to get Traffik to work when I've got internet set up).

I've used Gemini a lot over the building process. I think a lot of peoples issue with Ai isn't with the Ai itself but with the honesty, but I'm happy to be entirely upfront. Without Ai, I would not have been able to build this system. Even when I could write Python, I would have had no idea how to create some of the programs which Gemini has spit out for me, and quite frankly wouldn't have known where to start. I was able to get SMART passthrough working, I definitely wouldn't have cracked it otherwise, I made a script to spit out a list of real time specs which I was able to paste into Gemini which I used for troubleshooting.

I guess my point is 'yay, now I can watch movies without popups for the first time in years', but also 'this is an incredibly potent technology, with enormous potential to improve our lives'. I'm not even in CompSci, I'm a law student. What somebody with the background might be able to do boggles my mind.

Specs as of now:
Dell Optiplex 3050 Micro, Intel i7 6700t, WD Red NAS 1Tb NVME SSD, WD Red NAS 4Tb SATA SSD, 32Gb of Samsung RAM, and a Terramaster Dr-300 with two Seagate Exos 6Tb (combined to form 10Tb RAID 0 Array).

Future Plans:
Lazytainer and more Chron stuff for power efficiency (currently the hard-drives sleep, but I'm a student and I want to save as much money as possible), Traffik for front facing parts, DVD ripper, Github (vibe coding is version control hell), a wiki, NextCloud, and PiHole.

Tried my best at cable management but it's not as easy as one might think...
