I'm completely new to this and it's a bit overwhelming, so please bear with me.
I want to connect a HiFi Berry Amp2 into some form of a Raspberry Pi (not sure which yet), much like the guy speaks of in https://youtu.be/Dp_GfsA6o1o?t=132
1) It looks like it just snaps in, so I don't need any special screws or such attaching hardware?
2) With this HiFi-Berry/Raspberry Pi combo, what are my options as far as an enclosure case for the COMBO?
3) Last, but not least, my application MIGHT need a fan or heat sink to address temperature, so how would that come into play as far as such an enclosure case?
Any help would be greatly appreciated.
