The real thing printed, assembled, and painted
This took a lot longer than I’d originally planned, but it’s finally done! I decided to make this because I’m setting up a 4x TinyMiniMicro lab (Lenovo M920q’s, specifically), and I couldn’t find an easy way to get 3.5" storage for each node. There are some 4 bay JBODs, but they’re expensive, and wouldn’t let me split one drive per node! So I designed and built this over the last ~6mo.
It’s completely open source, from the source Fusion files to the custom SATA backplane PCB. It’s made to be easily printable and assembly was painless. Links to the models and PCB files are below. Want one of your own but don’t have a 3D printer? Or have a printer but don’t know anything about PCBs? Fill out the Group Buy Interest form, and with enough people, I’ll do a small production run and ship everything out at cost.
Features:
- 4-bay (19in rack) or 2-bay (10in rack) enclosures
- 40mm exhaust fan per drive for cooling air flow
- Custom backplane PC for “cold plug”
- Passive SATA connections
- PWM Fan Speed Control
- Power and Activity LEDs
- Steel rack ears
