## Assembly

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

#### 1. Thread all the profiles

#### 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.

#### 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.

#### 13. Wire up the raiser data cables
**Note:** Don't tie the cables yet, that's the last step.

#### 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](http://ethosdistro.com) to manage your rigs. The setup very easy and fast saving a ton of work when configuring / managing more GPUs.
