No heathsink on the demo board nor are there any holes on the PCB to mount it.

How is it possible that 10 GbE had become so energy efficient?

I am using an Orange Pi 5 (less known brand) and currently running a Minecraft server on it. I made a case for the Orange Pi 5 and the switch out of PLA, which I know isn’t very resistant to high temperatures, but I think it should be fine. Do you have any suggestions?

I have a HP Elitedesk 800g2 that I use as a main server for Jellyfin/NAS/Minecraft Server hosting and was wondering if anyone could give me some ideas to use the second Elitedesk and optiplex for?

Hi homelabbers,

Here is the long-awaited follow up to https://www.reddit.com/r/homelab/comments/1jh3bt5/first_rack_feat_my_own_3d_printed_rack_studs/

These are heavily inspired by Rack Studs, but designed from scratch by myself for 3D printing.

The STEP and 3MF models for the 3D printable rack studs are published on Makerworld: https://makerworld.com/en/models/1444742-rack-studs-unofficial#profileId-1504283

Print and use at your own risk. This kind of thing is not what today's FDM 3D printing is particularly good at. I'm sure that the comments section will help me out and explain how this is super dangerous and no one should use it for anything that's heavy or expensive.

If you have any doubts, please just buy the real rack studs. I made this because they don't sell them where I live.

Boat sensors DIY test bed with raspberry pi and esp32. No more mess on the dining table.

There is one raspberry pi5 with Bareboat Necessities (BBN) OS, one pi4 with Venus OS to test Victron interfaces, about 5 boxes are esp32 based NMEA sensors hubs one for engine and liquid levels, another for environment, another for electrical and batteries monitoring, another for alarms via WhatsApp. One NMEA 2000 to usb gateway. Boxes not attached are the ones that need to move during testing because they have IMU. Calibration requires movement. There is one for heading and attitude and there is another one for measuring boat heave. One box is pypilot motor controller which Sean D’Espagnier sent me to make sure integration with BBN works. Another with ink display is OBP60 which openboat guys sent to me for experimenting. There is also BBN m5tough display and headless coremp135 with BBN OS on it.

Somewhat of a homelab setup, albeit it is really, really, barebones... as you can see. It is nowhere near as elaborate as some of the other homelabs I have seen posted here. My goal is: I want to eventually consolidate the 3rd party apps my family uses for media, smart accessories, etc, and just put them all in one place - sort of speak. Here's what I've built today so far:

Server setup:

Running Ubuntu Server 25.04 on my old Lenovo Legion 5 Gaming Laptop (recycling old hardware that had some broken keys.) - Hardware stats are 2nd image attached to post. (Running about 20gb free RAM)

Configured static IP via netplan, mounted my external storage via SD (just what I had at the time laying around), and learned a little bit about "systemctl" and "ufw"/permissions.

Network tested a little bit when attempting to communicate with my Jellyfin media server and originally when setting up the connection with "curl", "ping", "ip route", and "lsof", etc.

Downloaded Podman, tried to run Jellyfin with it and kept getting Exit 139 error crashing, or (56) and or (7), resulting in complete disconnect from the service. So, not sure if I broke podman, or if it just didn't work for Jellyfin - so I switched over to Docker, installed that via APT and everything started working after hours of troubleshooting.

So, speaking of Jellyfin: created some config and cache volumes/directories for it, made the media directory and had to fight a bit with my local storage on my Macbook device and other Windows laptop after switching from Podman to Docker. Otherwise it went smoothly. Learned how to also use /health as an endpoint to debug container crashes a bit and in attempts to purge any corrupted configs I was facing earlier.

Security & Monitoring:

Installed fail2ban for SSH defense and configured my UFW to allow only essential ports, configured and changed passwords, password attempts, etc. Could use more work here honestly, suggestions are welcome. Cybersecurity interests me so system hardening is essential, I think.

What did I learn?:

A little bit of - docker, systemctl, ufw, curl, lsof, nano & vim, chown, chmod, and a few other little linux commands in the process. (Again, as the title states - I am a beginner. I just really started this as a hobby today.) Also did some local service stuff/debugging with /health again and localhost with some port scanning too.

Next up for my lab:

Nextcloud, Pi-hole, Home Assistant, and something for gaming potentially. Maybe more for media, such as Radarr or Sonarr. Just wanted to post and get some input/recommendations for next steps... Any feedback is appreciated. Thank you, cheers!

(Definetely almost rage quit a few times doing this and really struggled with setting up the container with Jellyfin properly. I spent a few good hours troubleshooting today.)

This is my closet home lab, nothing crazy but plenty to serve my needs.

ThinkStation P510 GPU Server

• Intel Xeon 12 Core
• 32GB RAM
• Nvidia Tesla P100 GPU (with 3d printed cooler & blower fan)
• x2 250GB Samsung Evo 970's in Raid 0

Used for Stable Diffusion and other AI tinkering

ThinkCentre M53 web development, NAS & backups server

• Pentium J2900 2.4Ghz Quad core (low end but has a stupidly low 10w TDP so can stay on indefinetly)
• 8GB RAM
• 2TB SATA SSD
• 4TB external HDD

Mostly used to web development and also sharing media across the network. I did have an old QNAP but this performs so much better at an even lower TDP.

I wanted to get into homelabing and decided to start with making a nas. It has 512gb of storage and is a bit slow but was fun and a great learning experience!

So when I started, I got a free 15 unit rack from a friend which at the time only had like a shelf, rack mounted PC, and an old Cisco catalyst 2960. As I started trying to buy actual servers, I realize that I did not have nearly enough depth so I had to upgrade, which is where the second rack came in. It was open frame 42 units and I paid about 100 bucks for it, at first I thought it was a scam but then I got it and I was like OK this is legit. then I was able to get a couple dell servers some HP servers two more switches. A dedicated firewall, and I mounted my monitor onto it. And I was fine with this rack, but then a friend made me an offer for his Dell Powerage 4220 cabinet so I took it. The coat was us trading racks and 200 bucks so like the sane person I am I took him up on it, now I have pretty much the exact same amount of stuff and everything but I have much more freedom to do stuff because now I have zero unit slots where I can put PDUs without interfering with the actual Rackspace so I’m pretty geeked can’t wait to see how much progress I make within the next six months. Oh and btw I started my homelab with an acer laptop and upgraded my way. The total amount spent so far just hit $1000, I got a lot of stuff for free or really cheap and deal hunt whenever I can. I have 5 servers, 1 firewall, kvm console, 3 switches, and a few chassis and minor parts.

This link shows my setup 3 years ago, I have got married and sold some of the hardware and moved some of my setup to another place, now I have 3 sites (Parent's Home (A.K.A. Site 1), My Home (A.K.A Site 2), and my In Laws (A.K.A. Site 3))

Changes from the precious setup:
- Sold 2 of the R730 since Covid is done and my students have now Lab PCs in the university thus my Lab has no reason to have so much compute.
- 4 Port Fanless Router broke down *snif* *snif* and moved to MiniPCs instead.
- Have now 3 sites, and using Omada for my networking at all of my sites.

Site 1 Details:
- Top of Rack switch a TP-Link T2600G-18TS for VLAN stuff and segregation for my security cameras
- Synology D220j NAS, most of the content came from CCTVs anyway thus I didn't put any redundancy.
- Dell MIni PC runs on Proxmox, that has LXC Containers that has Cloudflare Tunnels to expose the services publicly like the Proxmox Portal, a POS Service for my parents, a Wireguard Tunnel also for Site to site connectivity and a redundant site for my Web business
- Dell R730 I will move this soon but this runs test VMs and rarely used since I moved out I plan to move this to Site 2.

Site 2 Details:
- Synology DS418 NAS, backup storage from Site 1 also main Backup storage from all my devices, and the NFS for my Proxmox node.
- Dell Mini PC runs of Proxmox have the same setup with Site 1 Mini PC, but this is my primary site for my Web Business, which also runs Omada Controller for my Wifi Network.

Site 3 Details:
- Dell Mini PC runs of Proxmox have the same setup with Site 2 Mini PC but this is a Backup site for my Web Business.

Extra:
- I have a VPC that has a public IP which serves as a Wireguard Server to connect to all sites, since all sites have connection to this VPC I have an HAProxy to have a fail over for my Web Business, and exposing it through Cloudflare Tunnels.

I’m getting tired of looking at my cable mess so I decided to spend $2500 to fix it up. This is what I already have: a server for my business and one for personal use. The business one is a: Dell poweredge R730xd with 500gb of ram and a exon something. I forget but it’s for my Minecraft network and website. The personal use one is a: dell poweredge R320 also forget the specs. because I’m into home theater I have a Kaleidescape Strato V and AppleTV 4k for my movie content and a Raspberry Pi 4 running Home Assistant for my automation as well as a SofaBaton hub for my universal remote. I also have a Yamaha TSR-5830 natural sound AV receiver for my Dolby Atmos 5.1.2 and Dolby Vison setup as well as a UDM pro and UniFi 24 port Poe switch for my 6 U7 Pro APs. That’s what I’m moving over and what I bought is: 2 dell server rails, 2 AV shelf’s, 2 pass through patch panels, Dev Mounts, 2 StarTech PDUs, A SFP+ patch cable as my existing one is too long as I was dumb, normal Cat6 patch cables, 10 Cat6 6ft cables,10 IEC power cables, 2 15 ft extension cables as my outlets are too far and I need it to be on 2 separate circuits, 2 more Z-Wave smart plugs because why not, Govee RGBIC 16ft strip lights for a inner cabinet glow and lastly a SysRack 27U cabinet. I can’t believe the money I spent lmao. In the future I plan on spending another 2k as 5 Gig fiber is coming soon to my area and I plan on getting a new 24port Poe switch as it’s limited to 1 gig as I was a cheapskate, The ONT bypass SFP+ on a stick, A UniFi 8 port aggregation switch, 4 fiber SFP+ dual channels for my 2 servers, 4 Dual channel fiber cables, 2 SFP+ PCIE cards for my 2 servers, 1 RAID card as the server only came with one the R320, 1 SFP+ to Ethernet for my main PC. Then in the future future spend money on UniFi AI cameras and a UniFi doorbell. Well now you know my bad spending habits.
