HP DSP-600 PSU Mount on 2020 Extrusion Frame

I'm reworking my CL260 3D printer and we had an old server power supply HP-DPS600 on the job, which is stronger than my current one and can also deliver 5V for a Raspberry.

Since I wanted to fix it at the bottom of my 2020 frame, here is my solution.

A version upright and a variant (V2) lying as on the picture.
Had me for the attachment for M3 screws and T-slot nuts decided and holds super.
