I don't feel like there's much novel here-- as in, you could have built one of these in 2022.

The motherboard is a rebadged Ultimate 64 in white: https://ultimate64.com/Ultimate-64-Elite-MK2

Transparent breadbin cases have been out for a WHILE: https://www.retrofuzion.com/products/breadbin-case-set

It's got a mechanical keyboard, which could be a MechBoard64: https://www.retrofuzion.com/products/mechboard-64-fully-back...

The keycaps are slightly novel, in that they have a C= logo on the Commodore key. The guy from CBMSTUFF ran a multi-year project to produce new keycaps. For licensing reasons, his didn't have the C= logo on the Commodore key, but it's reasonable to think that they have taken advantage of his considerable work refining and producing the keys and provided a path to legally using the C= logo. Having one new key printed shouldn't take so much work as he put into getting all the legends correct on the others. https://www.cbmstuff.com/index.php?route=product/category...
