Designing a CPU is time consuming, actually building the CPU is extremely time consuming without automation.
You'll never build one in your garage powerful enough to compete with AMD/Intel due to their precise nano sized circuitry and 500+ million transistors, nevermind the security woes involved if you intend to distribute them. Depending how skilled you are in soldering creating a single prototype could take months to do. Actual products would take years to build by hand, and if you're not retarded hopefully its a low power design.
At best you could replicate a low end early 90s computer in processing power, build other computer parts and install linux on it.

I've been looking in to this some more, there's been quite a lot of progress on open hardware recently.
The lowrisc project have got to the point of a functional RISC-V SOC design that can be implemented on a mid-range ($320) FPGA board and boots a functional Linux system with basic text-mode VGA and ethernet.

This is still a long way from something powerful enough to run a desktop, but it does raise the possibility of other uses. Perhaps we could have completely open-source hardware home routers in the not too distant future. The FPGA development is ongoing while they work towards the goal of taping out ASICs for a fabrication run. I guess there will be some Pi-type boards made eventually.
I'm tempted to invest in one and have a play.
