I think it would have been better to faithfully reproduce the A1000 case and keyboard. Then they could have offered just the case/keyboard combo. That way retro enthusiasts would have something to tinker with, and anyone who wanted a genuine CUSA full blown computer could buy an entire system.
I think that now the truth is out and we know they're simply a "corner shop with a web-page" that there is obviously no money left to design and manufacture yet another case and keyboard from scratch.
There's no way of knowing how many C64x cases were manufactured and sold, but from the picture of the 1000x there's at least 3 left. I'll guess that sales fell way below expectations and no additional production runs were made. So, from a financial point of view it makes perfect sense to look for an off-the-shelf design and in this day an age there is probably just about every sort of desktop shape, size and colour available on the market. What really matters is what they put inside the machine and past experience unfortunately suggests that it will be under-powered and over-priced. If they do decide to do a kick-ass configuration then the price will probably make your eyes water.
The target market still seems to be the Linux user with more money than sense, an inability to build his own system and who used to be an ex-Amiga user.
That seems to be a hell of a limited market and I'm willing to bet that any Linux user who likes this case is more likely to buy a Wesena case, install his own motherboard and do his own engraving.
I'm guessing that the "franchise" option is their only hope for revenue and for that they need to convince people they have some products and designs to sell (even if they can't actually sell them).
and here's the Commodore Amiga 2000x:
