Empathy with machinery, particularly computers...

IMO there's just not enough time in life to learn about ALL the things, so at some point you gotta start picking and choose

It's that cursed gift of genius some have, so good at so many things, so curious and want to indulge in it all but yes, laser
focus on one thing and specialize in that until Mastery. 

There's not much inside a computer case. 
1. Power supply aka PSU
2. Processor(s) aka  CPU
3. Graphics chip or card aka GPU
4. Motherboard, aka MObo
5. Random Access Memory aka RAM
6. Data storage by either Solid State Drives aka SSD or optical Hard Dick Drives aka HDD
7. CPU cooler and Fan
8. USB Hub Control for functions like power, on off lights, drive access lights
9. Lots of fans (adoring ones at that). 
10. Cables coming to the MObo to various of the above listed components
11. You ( I know you can fit in there, let's be honest.)
