My pc :)

CPU: 500 to 600 micro controllers lost count, and 1 fire extinguisher.
PS: Several FETs and some coils of wire and controller
RAM: Some toroid magnets with wires through them who thought!
Case: some high temp concrete.
Mother Board: Wire wrap.
OS: After hooking everything together and a slightly modified satanic ritual to spawn evil in this world it called itself Windows. It might be related to Legion, like a distant cousin or something being that it is a plural name.
