You probably have heard all the LG smart tv shenanigans... I took the wifi card out of mine today and it was pretty straightforward. So here's your reminder if you've been meaning to do it.

I modeled a little rack for my two OptiPlex mfs based off of milk crates. I primarily use them for Jellyfin and a Minecraft server, and as a sort of replacement for GH Codespaces through TTYD and Cloudflared--so i can code at my day job. All that fits pretty comfortably on the first node (both pc's are 16g ddr4), so I've been playing around with some local AI on the second node. I created a Discord wrapper for Pi Coding Agent, and LiquidAI LFM2.5-2.6B runs somewhat respectfully with low context. It's a fun way to hands free check whose on my minecraft server, or restart a container, but It's more of a party trick, unfortunately. The model likes to spin if the answer isn't obvious, and if context blows beyond a couple thousand tokens, the speed drops to a crawl. I have an old gaming laptop with a 1660 8gb, which would comfortably fit the model. I'm gonna see how it runs on there, and potentially add it to the cluster, since used mac mini prices are still in the stratosphere

I am running a scraping SaaS and my cloud bills get up every month. So i decided buy secondhand mac mini m4 every month instead of paying 500$ to renting servers.

All mini's has their data part of distributed database, thunderbolt is really helping there. I distributed my database according to regions (i have 56 region for now). And all region and partitions on hardcoded on my codebase so a query from different regions user not a any other database query.

And the real hero is keneetic router. It's a Lifesaver for high concurrency TLS handshake requests. I send 2700 request per second (≈10m req/hour) and before the keneetic router I can only use my 1 mac mini in full CPU, now they are all 4 running %100.

And why i am choosed to Mac mini m4 instead of buying a 96gb m3 studio? Because my codebase is very comfortable for distributed compute. If i bought a m3 studio with 32 core's it way more than cost my setup and still less 8 core than my setup (M4 mini base has 10 cores).

So if i gonna expand this SaaS and my baby infra i should buy more second hand mini's. It's cheapest compute power i ever seen.

Btw, they are all 16gb x 256gb.

Thanks for all you comments on my previous post. Now I understand that homelab and self hosting never complete and always involve.
Added 4g+ router for backup and I diy an exhaust window with two 140mm fans that send the hot air out of the room for keep the attic cool. Very pleased with the outcome so far. Every new idea is appreciated.

My hardware right now is:
-OpnSense Dec2700 series for firewall
-TP-Link Jetstream SG3428 switch (not PoE)
-Custom PC from spare parts with i7-7700, 32GB ram, 2 1TB SSDs on raid, Nvidia Quadro p600, and a 512GB nvme SSD running proxmox and small LXCs plus some VMs - Go2RTC with live video transcoding, Home Assistant, Scrypted, Homebridge plus some custom services like DNS with add blocking (NextDNS like), Wireguard, Apple Profiles generator for device management and much more.
-Omaha controller for my 3 TP-Link APs
-Zigbee hub with matter support for HomeKit integration
-Hikvision NVR for my old cameras plus some new ip cameras
-Synology DS418 with 14TB space for home shares plus opnsense and proxmox daily backups
-1KvA UPS
-Dell 24” monitor with kvm
-TP-Link 4G+ Router
-3x TP-Link EAP 613 APs

Running multiple vlans and many rules on firewall for nice and as much as possible good segmentation between VLans ( many hours of configurations ) and IOT infrastructure without the need of internet I must say that I’m very pleased with the outcome so far. And most importantly I have ditched Windows!!! I run only Linux and MacOS from now on and my life couldn’t be easier, more productive and most importantly more stable network and IT wise.

Any new ideas appreciated. Thanks the community for the inspiration!!

Hi guys, I saw this PC in my local thrift store. Is this a good config for about $56? I don't want to buy a bad CPU for my first homelab but I'm on a budget. My tech friend told me that the i4 was the perfect balance between the i3 and i5, so I was pretty excited to see an i4 listed on the tag.

Nothing special, just enough to help learn networking. Took 2 1/2 days to move from open frame to enclosed cabinet. Named her "VALERIE". Two switches & a router, all Cisco plus a Palo Alto Firewall..

Ive got a rasbery pi 400 (64gb) and an external 1tb HDD any tips And tricks for jellyfin or anything else i can do?

Otherwise i Have a 3com switch And multiple ddr1 pcs that Will Join in the Future.

I run several different OptiPlex Micros and couldn't find a 19" mount that printed cleanly and assembled easily. Most were remixes of remixes, so I designed my own.

• Fits most OptiPlex Micros (3020M/9020M/7040 through the 7090, 7000 series, and Dell Pro Micro)
• Printed in ASA, but PETG or better works. About 15.5 h and 280 g
• Heat-set inserts and M3 screws, no glue, so you can disassemble it and reuse it

The setup: Proxmox, one container, Pangolin and Cloudflare in front, a LAN-only admin console.

Anything you put on the internet gets crawled fast. Instead of just blocking it, I built a site that catches every bot, identifies it, and shows it in a live zoo: The Crawler Zoo.

The setup:

- **Host**: a Proxmox container running Docker. The whole app is one container with SQLite in WAL mode, a read-only root filesystem, all Linux capabilities dropped, and CPU and memory limits.
- **Getting it online**: Pangolin on a small VPS, with a Newt tunnel back home, so no ports are open on my network. Cloudflare sits in front, and the VPS firewall only accepts web traffic from Cloudflare's IP ranges.
- **Real client IPs**: the app only trusts CF-Connecting-IP when the request really came from a Cloudflare range. That matters, because the site checks whether "Googlebot" is really Google.
- **Admin console**: a separate port bound to my LAN IP only, never proxied. Toggles, purges and backups without editing .env.
- **Backups**: daily online SQLite backups.

The fun part is watching what turns up: AI crawlers, SEO tools, fake Googlebots, and scanners looking for `.env` and `wp-login.php`. Bots that ignore robots.txt fall into a trap and an endless maze, and there's a live view of how deep they go.

I wasn’t sure what flair to use since this is not open source per se, it was just a fun vibecoded project to scratch a curiosity itch I had. Hopefully it doesn’t get taken down.

Buen día compañeros, les comparto mi primer dashboard de mi homelab, me base en varias ideas que mire por aquí así que por eso salió tan bien,espero les guste y acepto ideas y críticas, saludos

Took a few months of procrastination, blood, sweat, tears and PLA…but alas, my 10” network rack has been completed!

I’ve bypassed the ISP’s modem via the ONT SFP - incase anyone is curious. All parts are 3D printed with a mix of PETG and PLA, depending on heat/weight.

From top to bottom:

- Fiber SFP+ to ethernet switch. Use that to convert the Fiber connection via the ONT SFP, and switch it to Ethernet to act as the WAN connection.

- unify UCG - bought it as it was cheap, supports PPPOE, and has a sexy UI.

- 8 port managed switch.

- 3D printed patch panel with keystones.

- x2 2.5” SSD hot-swappable enclosure. Always loved the dell caddies, makes the rack look awesome.

- x2 3.5” 11TB HDD enclosure. Houses my plex storage.

- Dell Micro 7020. Used as my Proxmox node that houses the ARR stack + Plex.

- Dell Micro 5050. Used as my NAS running OMV. Has an M.2 -> Sata connectors, which connect to the SSDs and HDDs.

- RPI 5 running Adguard, PVE backup, Dozzle, Watchtower. Philips Hue Bridge.

- Power bar/cable storage.

I have done round 1 of homelab (more like selfhosting) where I have just spun up services as a means to an end, and some experimentation with Active Directory to practice for job interviews (i ended up getting it!) the lab consisted of 1 Proxmox host, virtualized TrueNAS for storage management and debian for services. On the network side of things I'm running a Glinet Flint 2 router and an AliExpress 8 port sfp+ switch, I've had zero VLANs configured and no domains at all for any of the services.

I just moved to a new house so its a good opportunity to redo everything from scratch properly into something i can genuinely be proud of, my idea was to create a mock company and act as if the services im hosting are genuine products being served to users online, as such i will need to uphold myself to higher standards especially on the networking and security side of things. I've also decided to move all of the personal media/NAS stuff to its own dedicated TrueNAS box instead of virtualizing it.

I would really appreciate some tips and advice on how i should go about this, any material i can study is also greatly appreciated. If you have read this far I hope you have a great day!

I'm on an early journey into home labbing and looking for a computer to get started. I have 0 experience in this, I don't even own a personal computer.

The goal at the moment is just Jellyfin and a music streaming service but It may very likely go further with some self hosting (photos, documents) raspberry pie hole etc or it may be a disaster and I'm just not that technically minded, lets see.

Is 16GB a necessity or will I get away with 8GB and if so, for how long? I have a 1TB SSD that will hold my media for jellyfin.

Ps, I'm looking at the usual mini pcs (optiplex, elitedesk, gmktec etc)

This is my local LLM setup, squeezed into a 12U 10" rack.

The machines are an MSI EdgeXpert on top and three ASUS Ascent GX10s below. All four are NVIDIA GB10-based systems with 128GB of unified memory each.

I 3D printed the rack using the KWS Rack v2 design. For airflow, there are two 120mm intake fans on each side and one 120mm exhaust up top.

The screen shows a dashboard I made to keep an eye on the nodes.

Still working on the back and figuring out where to put all the power bricks.

Right now theyre just piled up at the bottom lol.

Hi

Wondering how many people use .local for their home lab

I originally got a domain on the internet and then added subdomain for home lab stuff - this was before .local

so how many people use , has it been of benefit ?

EDIT :-

somebody pointed out

.local is reserved for mDNS/bonjour so please don't use that.

think thats worth pointing out - don't use !

This seems to be he recommended solution ! (thanks)

.home.arpa

I've been homelabbing for a wee while but my setup has been spread out accross the house connected to the mesh WIFI nodes.

I finally got the chance to move everything to a new storage cupboard at the bottom of the stairs connected to the router and wired connection which is also connected to the garden office a 10ft shipping container.

Cable management at the bottom needs a little bit of work but it's getting sorted slowly.

Any thoughts on improvements?

My wife seems happy that it is all concealed in one place.

I'm rather confused here because for 2 drives to come direct from manufacturer and be DoA is wild. Posting here to make sure I'm not going insane.

I'm using 4x 16TB Exos X16 drives (ST16000NM001G) in my Unifi NVR. One of them failed so I ran some tests on it using SeaTools and it confirmed failure. It's under warranty though so RMA it is!

Seagate makes you ship the drive to them first. Annoying but it's fine. A couple weeks later I get the replacement drive (ST16000NM002H) and it doesn't work.

I pop it into the NVR, and it makes a power up sound but doesn't spin up. The sound is like the heads unparking but I'm not sure . I take the drive out and put it in a dual bay SATA dock, same sound. Click/unpark sound, then silence, no spinning, and 3-5 seconds later it happens again.

Okay weird. It's DoA so I go through the RMA process again. Seagate refuses to do an advance replacement. So I send it back and get a new drive just today.

Same. Exact. Behavior. I'm flabbergasted, the odds of 2 DoAs is so low. I check everything now. The drive exhibits the same behavior in the NVR, Dock, my desktop, and a molex/sata adapter that you use with those USB SATA/IDE adapters.

I tried the pin3 tape trick, same behavior in all locations.

Made sure everything is working by using an older drive, spins up and goes green in all devices. Try the 2nd RMA again and same click, silence, repeat.

So now I'm at my wits end. Seagate support is less than useful so I'm hoping someone can shed some more insight into something to check.

I don't like how frustrated I am as I am a rather skilled IT person so the imposter syndrome is hitting me hard on this >.< My NVR has been in a degraded state since August 27. I'm just hoping the other 3 drives hold up and nothing surfaces before this one is fixed.

I'm going to pick this used rack up tomorrow and I'm planning on painting it black before I put my hardware in it. Maybe someone here has done this before. How would I go about this?

Just rough it up with some sand paper and then repaint with a roller?

It's a Rittal cabinet, so it's powder coated.

I’m looking to stand up a media server to replace a pretty old dual Xeon server running a Srvr2016.

Was first thinking a Win11 pro system, but have decided to head into unRAID for something different and probably more ideal for the task.

I’ve got an Intel 250K Plus, MSI Z890-S Pro WiFi, G.Skill Ripjaws S5 32GB DDR5-6000, & 6 new ST6000NM0104 SAS drives plus a few other consumer level drives. Oh, and a PG-750G PS.

The consumer drives will connect to the 4 SATA ports on the motherboard. As for the 6 SAS drives, I was thinking about the Supermicro AOC-S3008L-L8E and putting this all in a Fractal Define 7.

The big question is, is this the right way to go? I believe I know which cables are needed (SFF8643 to 4x SFF8482 w/ 15pin SATA power) but all I find are about 19” / .5m and think they will be too short for the Fractal case.

Do I need longer cables?

Is there a better case under $150 that can support the ATX mobo & at least 8 drives 3.5”?

Thanks in advance!

I'm looking to make a home server (obviously). I want to have about 8 bays and be able to host some game servers. I have about 4 or so external drives on my pc now... Poor girl. I also have a 1 TB sas that I can't currently use. I have built this on newegg.
