I disagree on being 10x harder. Bicycles are the same concept just older. There is a frame (computer case/mobo) and you bolt on compatible parts like brakes, cranks, forks, wheels, etc. (cpu/memory/gpu/psu)

I'm sure if you talk to someone working at a bike shop they could take your comment, flip it, and still have it be accurate:

Two of my friends build PCs from scratch, but they find building a bicycle difficult. I argue that their hobby is ten times more complex than building a bicycle nowadays, as everything is mostly plug-in-play and idiot-proof. Truing your wheel or overhaul a hub is a walk-in-the-park compared to installing the CPU.
