Thank you for checking out my project. I encourage anyone who wants to alter the design to make their own connecting rails so that it can hold as many pi's as you want. The enclosures slot into each other so you can vertically and horizontally scale up or down to whatever suits your need. This post includes the core enclosure, and the enclosure for the TL-SG105 network switch. The hardware required for the project as well as the amazon links are listed below.

As of right now I haven't made a build guide but I plan to in the future. If you run into any issues, please message me and I'll do my best to respond quickly. If you make one, please post the make. I look forward to to seeing the expansions people make to the design.

### Hardware Used ###

12v DC Power supply with a minimum of 10amps
qty - 1

M3 Machine Screws - Amazon Link: https://www.amazon.com/gp/product/B07CYNKLT2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

M3x12 - qty 12
M3x6 - qty 8
M3x5 - qty 4 per sbc tray

Buck Converters - Amazon Link: https://www.amazon.com/gp/product/B07RVG34WR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

qty 4

Note: These will not come preset to 5v, you will need to do that. Then connect 4 in parallel to give you 12amps. That will support your 4 sbc's if you're using Pi's or Libre AML-S905X-CC.

DC Solderless Power Jack - Amazon Link: https://www.amazon.com/gp/product/B015OCV5Y8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

qty 6

Misc:
I made my own micro usb cables to power the sbc's. If you'd like, you can use some cheap right angle power cables as long as they're thin enough that they don't run into the top back connector. I've got all of mine terminated to a male barrel jack that to connect to the power module's female barrel jacks.
