There are two types of homelabers. Those who have a 19" rack and those who will get a 19" rack.
My original system worked great for years, but I decided to upgrade it so its mostly 3d printed and requires no aluminum extrusion and a lot less hardware overall. The most notable change is the addition of a fully 3d printed 19" adapter that utilizes nothing but m3 screws to hold all the individual drawers in. There's significant ventilation in each drawer to help with cooling!
Note: raspberry pi cluster is designed for these cases in particular top_low_fan40_poe. I also strongly suggest POE hats if you plan to use this cluster, and a fan is a must (Noctua 40mm fans are GREAT)!
Power Distribution Unit:
DANGER: This requires you to work with mains voltage. Mains voltage will kill you. If you do not know what you are doing. Maybe skip this one. I am not responsible for any injury.
Bill of Materials:
- 3x 8 port Wago Push Connectors (Amazon US)
- 6x Panel mount US sockets with ground. (Amazon US)
- 1x Fused C14 inlet. (Amazon US)
- 6x heat set inserts (Amazon US)
- 1x Power Distribution Insert
- 1x Power Distribution Lid
- 6x m3x10 screws
Build Instructions:
- Seriously if you didn't read the warning again, this requires experience with mains voltage, if you are not comfortable doing so, don't build this. I am not responsible for any injury.
- Read step 1 one more time
- Fine I shall continue….use wire cutters or flush cuts to cut the sacrificial bridge on each of the locations for the panel mount sockets
- Install the heat set inserts on the top for the lid, as well as in the large square opening for the power inlet
- Snap in all 6 panel mount sockets
- Screw in the inlet with 2 m3x10 screws
- Wire colors don't always match, please verify your live, neutral, and ground wires, there are multiple standards for wire colors.
- Connect the live wires together via one wago connector
- Connect neutrals via another
- Finally connect grounds with the final wago
- Verify your wire connections one more time
- Use the remaining 4 screws to screw the lid on (please don't plug this in with the lid off, there's lots of exposed mains voltage still.)
