BUT..... you can't buy anything like a cyber deck. Search Amazon, eBay, Google Shopping - nothing. Not one single company manufactures anything like a cyber deck, in any form at all.
All hardware manufacturers make is the same old rectangular boxes. There's a very small number of unusual shapes, including one pyramid. But for the most part even these "unusually shaped" cases are basically the same old design, pretty much a box with a motherboard in it, with unusual angles on the box.
Why is there so little innovation in computer design when the hobbyists are clearly showing what people like and are interested in?
I've thought about building one for myself, but unfortunately I have no idea what I would do with it. They look so cool, and I have a prop making background... but there lots of other creative and decorative possibilities for that much money. It seems super niche, since so many just... aren't practical for most.
Maybe a more marketable version would be a cyberdeck shaped tablet dock. Sized to fit a tablet with a rugged case. Instead of a true "cyberdeck", a device that looks like one, and fulfills the real life role that they have in the movies.
More of a "Tech center", a portable WiFi hotspot, with some wireless charging docks, solar, a NAS, a Home Assistant hub, convenient tablet controlled place to dump your digital photos onto the NAS, maybe 5G hotspot, etc.
Maybe you could skip the keyboard completely, and not even try to be a device for extended typing. With the tablet mounted, it would serve as a smart display or kiosk.
Maybe they could serve as Meshtastic hubs too, along with WiFi mesh nodes.
