Digitus 12U Rack Build

[beatles1]

I've been moving more services into the house that I used to run externally but the cupboard they were in wasn't really fitting them any more. I got a Digitus 12U rack and have migrated everything into it.

This rack doesn't have much airflow and no access other than at the front. To resolve this I cut two 120mm holes in the back with a hole saw and mounted fans there. Turns out that's actually quite hard work but I got it done in the end!

The rack has
1x Unifi USW-Ultra 8 port switch
1x MikroTik RB260GS for OOB management links
4x 8TB HDDs
1x ASRock J5040-ITX
1x Unifi Flex Mini 2.5G
3x AMD Mini PCs
Power bricks at the bottom

The uplink from the Firewall goes into the back of the USW-Ultra via a POE Injector.

On top is a Unifi AP, a POE powered Zigbee adapter and an Ikea Tradfri hub.

The J5040-ITX is connected to all the disks and runs Unraid because I had a spare licence I wasn't using any more. That then has a Proxmox Backup Server VM and might in the future have some shares for big files. This is all mounted in GeekPi shelves and I did notice the holes in them aren't big enough for normal rack screws etc. With the rackstuds I'm using they just about go on but it's not ideal. The HDDs needed some 3d printed springs to mount on so that they're not vibrating everything.

The 3 hosts are a Proxmox Cluster with the Flex Mini 2.5G to give them a bit more speed for replication.

Everything will eventually have NanoKVM (or NanoKVM Lite) but currently it's only the Unraid box which does.

Cable management isn't great but it's functional enough. There's a UPS on the floor which it's all connected to.

Unfortunately because of where my internet comes in it still makes sense to have the firewall there so I can have some network ports there without hairpinning in a 1gbps link to the rack. I do need to find a small UPS solution for that and the ONT now the main UPS is with the rack.

Apologies for the crappy photos:
