From the top:
- 3 Chinese 2.5Gbit managed switches branded Horaco
- 3 Chinese N100 “NAS” ITX boards (the cheaper green ones). They are in a Proxmox hyperconverged cluster (HCI)… aka Proxmox + Ceph.
- Each one has a Pico PSU
- a PCIE card (mounted on an right angle PCIE extender) with 2 additional 2.5Gb realtek NICs
- 2 NVMe drives (mirrored boot drives)
- a SATA SSD for Ceph
- an empty shelf for a ITX board (an AM4 with a bunch of NVMe drives I have yet to move from my previous rack)
- the last shelf can accomodate:
- an automotive power distribution that feeds 12V to the switches and the N100 boards
- a couple of 12V to USB PD boards, that I use to power the type c devices on the Rack shelves on the back
- a (missing) TFX PSU that will power the AM4 board
- a second TFX PSU that feeds 12V into the distribution blocks and powers basically anything else.
I also have some rack shelves on the back:
- a Pikvm based on a Pi2 I had laying around
- a wled controller for the fan lights + a esphome temperature based fan controller
- a Sonoff Dongle M
- a IEC C13/C14 power strip that distributes power to the PSUs
Needless to say I bought everything before the DRAM craze and I feel very sad for who has to work with the current market.
Everything is mounted on custom 2U or 3U 3D printed 10" rack shelves.
I’ve just bought a few pack of these 8x8x500 sticks. And yes I tried some wood glue from the hardware store and they simply stuck very well to the PETG prints.
