Raspberry Pi 5 + Waveshare HATs

I've been using raspberries for to drive my domotica systems for quite a while (3, 3B+, 4).As systems are continuously being added I felt the necessity to regroup them in one machine baring all the interfaces. Requirements:Central Unit: Raspberry Pi 5 4GBPoE powered (HAT 1)PCIe M2 SSD (HAT 1)Additional USB ports (HAT 2)RS485 (HAT 3)CAN bus (HAT 3)So I opted for a couple of waveshare HATs, that includes all the above, their metal case not being big enough for all of them I had to make on up, hence this model. After quite a few iterations (getting the holes at the right place was no too easy) I came up with this reasonable box for the stuff above. There's a hole for a power button but I'm using a paper clip at the moment.
