Raspberry Pi 3 + Raid 1 (2x2.5" disk room) case

This is a first try for making a case for one raspberry pi 3 and 2 2.5" disks so that you can do some Raid 1.
Assuming you are using 2 connectors like [this one](https://fr.aliexpress.com/item/USB-3-0-to-Sata-adapter-converter-cable-7pin-sataIII-to-USB3-0-adapters-for/32830988939.html?spm=a2g0s.9042311.0.0.27426c37xWGQgn) for your disks (actually, you won't need USB 3 connectors, USB 2 is enough but mind the size)

**Edit**: added on the top part a flush mounting edge and a hole to let an Ethernet (or an external powered USB hub) cable through

Photos of the prototype show that there are still some fixing needed: Not enough room for the fan pins between the top and the board, not enough room at the rear for the usb sata connector cable, fixing parts too fragile...
