MicroATX blade

thingiverse

This microATX blade system serves as a natural extension of my previous NUC shelf, which was fully 3D printed. The two components are designed with OpenSCAD and offer full customization options. We required a solution to accommodate microATX motherboards due to memory capacity constraints and the need to utilize AMD Ryzen processors with ECC. The shelf boasts seven servers within six rack units. The board is a laser-cut piece fabricated from a 1mm steel sheet, available in dxf file format. To assemble this system, you will need: - Two U-rack brackets (x2 per shelf), such as the K&M 28482 19" Rack Tray 2U - Twelve 3D printed supports, available for download as an STL file - Epoxy glue - Seven laser-cut steel boards, designed in dxf file format - Seven 9mm spacing screws (4-5mm) to secure the microATX board, sourced from AliExpress - Cable ties (8-10mm width) to manage PSU and disk cables (if not using NVMe/M.2), found on AliExpress - Seven switch On/Off/Reset ATX units, available on AliExpress - A FlexATX PSU, such as the Seasonic SS-350M1U The boards are held in place by the two rack brackets, which feature simple glued supports (two lines). Each board is inserted into a support notch. This system offers ultra-low-cost efficiency, with an online laser cutting service providing steel boards at approximately 15 dollars/Euro per unit.
