I plan on trying to build a simple computer like something from the 80s but I eventually want to move on to something more powerful then the raspberry pi.
How much time and money do you have?
First there is the design, back in the old days when clock speeds were low and noone cared about EMC laying out boards was just a matter of laying out tracks to match a scematic. Nowadays that's no longer the case, layouts have to manage high speed signals where the behaviour of PCB tracks is far from the concempt of an ideal wire, very high signal densities and a need to keep lines from power pins to the decoupling caps very short. Honestly lots of board designers just copy the SoC vendors reference design for the critical bit arround the SoC
Then there is the board manufacture, you are talking multilayer boards, often with blind vias and with very small feature sizes. That doesn't come cheap in low volume.
Then there is the assembly, if you want to do this yourself you need microscopes, placement tools etc if you want to contract it out expect to pay, especially if the SoC you choose uses PoP
If you are really interested in this stuff I belive the design files for the beaglebone black are available and would be worth looking at to get an idea of what is involved.
