Yes. Yes. Yes, but it would be huge, inefficient, take weeks to solder together ( I can't make PCBs) and run hot as hell.

I mean, you can solder together all the components to make a simple CPU, but again it would be huge, hot, and horribly slow. I wouldn't want to try even as a DIY LimitBreaker.

Q's for you: Can you run an OS on a PC with no hardrive?

A 100uf capacitor has blown on your motherboard, but you only have a 20 pack of 10uf capacitors on hand. What do you do?

Will your computer work with 2 8gb ram sticks at 2400mhz and 2 8gb sticks at 4200mhz?

Does an SD card or thumb drive count as a harddrive? If not, I got this

EDIT: I think I got this. You either have to connect them in series or parallel

Ya got it. You can boot from a live usb/cd, and you can also load an OS into your RAM over the net, via Pre execution environment or an equivalent.
You'll need to run 10 10uf capacitors in parallel to replicate a 100uf cap. In series, the total capacitance will be less than the sum of the smaller caps together; in parallel they effectively become one big 100uf cap.

Good OP man, this has been kinda fun.

Your computer can't use RAM at different speeds. It needs to get its data at a somewhat even rate: if you get one byte in 30ns and the other takes you 42ns, then your CPU can only process the data after its got the whole thing, that is, after 42ns. So... You can USE 4200mhz RAM along with 2400mhz RAM, but you have to run it at the lowest speed and highest latency settings supported by any of the sticks.

Correct, and most modern PCs will detect the difference and default to the lowest usable speed.
