The C-one is a reconfigurable computer. It has two FPGA's as processors. You can put a program inside the FPGA's. The program can emulate a processor. For example it can act like a C64 including all the chips inside the C64.

The C-one is placed on the removable backplane of the case. Note that there are two metal strips removed from the PCI slots. The strips are in the way because the two audio output are slightly in the wrong place.
