Simple Makerbeam SFFPC

10mm MakerBeam parts required:
8 or 10 T-Nuts (you'll need 8 if you don't want to use the USB mount or 10 if you do)
4 or 6 M3x6 screws (for the T-Nuts securing the motherboard rails and the USB mount if you use it)
5 300mm Beams

Non-MakerBeam parts:
14 M3x10 screws (with head no larger than 6mm diameter)
1 #6-32 Nut (should be 1/4" across the flats and 3/32" thick)
1 #6-32 Screw (3/8" long)
4 #6-32 Screw (1/4" long)
2 M3x13 or M3x15 screws
2 M3 nuts
4 M3 motherboard screws

Some Notes:

GPU width maxes out at about 60-62mm depending on exactly where the GPU is that wide.

Using the long caps the GPU can be up to about 335mm long.

Using the short caps the GPU can be up to about 305mm long.

CPU cooler can be about 125mm tall, just make sure it doesn't extend past the edge of the motherboard or it might hit the beam if you're using one that's that tall.

PSU should be SFX.

The USB mount I have included fits some random USB port I found online at some poin
