raspberry pi 4B desktop case

This is a desktop case for the pi 4b.
Most cases only hold the pi, power supply and oher equipment need their own cases. I don't like these as they are not stand-alone and you have lots of cables laying around.

This case holds a 5v 4A power supply available from a.o. aliexpress and can hold upto 2 SATA disks or 1 disk and a power backup-unit. Also there is a space for own equipment. For me I also added a fan and a small amplifier with 3W speakers (3.2cm mount). I used a 12V fan, with a step-up converter I changed the 5V to 9V which is still almost noiseless but gives more cooling than just 5V.
There is space between the case and cover to allow a flatcable from the GPIO's to an expansion board

There a several 4mm holes, 1cm apart, to mount own devices
