Pendeo wooden case and monolith interface?

I saw an ad online for a very cool looking hardwood case and a “monolith” interface for quarter inch audio cables and USB made by a company called Pendeo. I went to the website, but sadly they are sold out, with no indication if they intend to make more! Was thinking that the case itself would not be so incredibly difficult to build a facsimile of, but being not an electrician type, the interface would be a different story. Anyone know of any other products out like this, or know of another place where the monoliths and cases are available?
