Assembly

Note: Any dimensions are measured on the inner parts of the frame.

1. Thread all the profiles

2. Put M4 nuts into all printed T Slot nuts

3. Place the T Slot nuts in the following profiles:

* 2x 6 nuts in 500mm
* 7 nuts in 500mm
* 3 nuts in 400mm
* 4x 2 nuts in 300mm

4. Screw the frame together using the M6 screws, 300mm+500mm profiles and the 2020 Corner Connectors

5. Screw the PSU frames to both power supplies

6. Screw the PSU support Right Angle Brackets

Note: ~116mm from the back.

7. Screw the MOBO standoffs and MOBO

Note: Leave ~100mm on both sides.

8. Screw the PSUs to the main frame

9. Screw the raiser beam using the M6 screws, 150mm+500mm profiles and the two 2020 Corner Connectors to the frame using Right Angle Brackets

Note: 100mm from the front.

10. Screw the Raiser Rails to the beam using M4 screws

Note: Place the first one by the left edge and then space other ones 44mm apart.

11. Screw the GPU Bracket Rails to the upper part of the frame

Note: Place the first one by the right edge and then space other ones 55mm apart.

12. Screw the raisers to the Raiser Rails with M3 screws

13. Wire up the raiser data cables

Note: Don't tie the cables yet, that's the last step.

14. Wire up the raiser and MOBO power cables

15. Place all the GPUs and screw them to the GPU Bracket Rails

16. Wire up GPU power cables

17. Boot up and check if everything works correctly

18. Use zip ties to clean up the cables

I recommend using ethOS to manage your rigs. The setup very easy and fast saving a ton of work when configuring / managing more GPUs.
