Seeing as I will be running the Pi 3b+ as a arcade machine, I figured it might be a good idea to add a small heat syncs. I did consider buying a heat sync case for it. They look great but this pi will be eventually hidden on a cabinet.
I did in fact order a case of this type then swiftly cancelled the order as I concluded that with the scarce availability of the “ipac 2” usb encoder “as used in my friends arcade machine”, I may end up using a Pi hat usb encoder. If that proves to be the way forward then such a case would not fit. Therefore I am holding off ordering a case until I have decided on my way forward.
