Fits three GMKtec NucBox M5 Ultra or M5 Plus mini PCs across one 19" rack row, 2U. The row is three printed pieces, each with its own cage, that bolt together into one full width bracket, so a three node cluster takes a single rack row instead of three separate mounts.

FITS

• GMKtec NucBox M5 Ultra
• GMKtec NucBox M5 Plus

These share the same chassis, so any mix of three fits.

⚠️ Before you order:

• Check the label on the bottom reads M5 Ultra or M5 Plus. GMKtec use the M5 name across several machines and this one is cut for those two.

WHAT YOU GET

• All three printed pieces, plus the hardware that joins them at the two seams. The three are a matched set and bolt to each other.
• Rack screws are not included. Use whatever your rack takes.

MATERIAL
3D printed in PETG, not PLA. Three mini PCs working in the same rack row put out real heat, and PETG holds its shape where PLA would start to soften.
