Here's a closer zoom of the mainboard. This particular mini-ITX is Intel Atom-based with a D2700 CPU, but it is possible for a customer to order other more powerful PC configurations from Commodore-authorized resellers, and to order the C64 in a barebones casing only.
Here's a Commodore 64 being built.
Along with the casing, the keyboard for the Commodore 64 had to be reproduced and re-designed, including creating all new injection molds for the keys. The keyboard mechanism itself is of the high quality buckling-spring type used on 1980s-style IBM PCs and the original MOS Technology 6502-based Commodore 64.
