Aluminium extrusion 80/20 Mining RIG (GPU Support rails )

[Aureliusy]

I would like to make my own mining rig (again).
Would like to use Aluminium extrusion  or 80/20  

Seen plenty of examples, but I can not find  the part that is used for the GPU Support rails. (For attaching the GPU with screw)
Anybody know the name of the part or maybe a webshop where you can buy them?


Thanks

See examples (of I think two different kinds)

One of the ones you're indicating is just flat aluminium bar and you can buy that anywhere really.

Couldn't you just use a 2 slot 80/20 for the other one?
