KKSB Cases Raspberry Pi 4 Case Aluminium | Active & Passive Ventilation | Easy Assembly | Space for High Coolers | For Raspberry Pi 4 | Space for Many Hats

I bought this enclosure in order to fit a Raspberry Pi 4b along with a heatsink , Can Hat and a couple of GPIO adapter boards inside for a Home Solar System Controller running Victron Venus OS.I could not find any other enclosure that would fit all my parts inside and keep them away from accidental damage or prying fingers, I'm suprised no-one makes a modular, extendable case system yet for the Raspi, so many people out there must be after something like it.However, as many others have said, it's an absolute pain to get your parts in and the screws tightened up, the fitted supports on the base are M2.5 so straight away you're restricted to the hardware you can use, then getting all the parts in place and still be able to fasten the hardware up is a feat worthy of a gynaecologist.It works for me (so far) but if I need any more hats I'm going to need a bigger boat.

I used this for a Pi4 and LoRaWAN card with added heatsink and fan for the Pi. The case holds the build and there was plenty of space for adding a couple of SMA connectors but it is a bit thin on the metal content and is a pig to work on as you need to flex the case quite considerably to get the Pi to fit. Also worth knowing is you need to assemble your Pi build with only the Pi main board installed in the case and everything else fitted after as nothing else will fit through the side gap if it is attached to the header pins so get all your sideways tools ready and have a few quid handy for the swear box. Not the worst case I have used in terms of utility but vastly overpriced for what you get.
