Wouldn't be too hard to replicate that. And you could easily keep it around $200. Raspberry Pi, a cheap LCD monitor and speaker. You could lose three buttons and use a curved layout (9 straight buttons, really?). Get a JLF with a Link so you can close the box.
Looks really slick (aside from the buttons), but that's just way too much money for what it is.
I think he's charging so much because it's a lot of custom work. If he's doing all of it by hand, 3K pounds isn't unreasonable.
Of course, materials don't cost anything near that. And, personally, I think paying someone to do it would take most of the fun out of the idea. But, if he doesn't have an external shop that can deliver him parts, then it'll cost quite a lot to make it worth his time.
I agree that the layout seems very odd. There's obviously some games he has in mind. I've never understood why these things don't have modular set ups. It wouldn't be outrageously difficult to make it so the sections pop out.
The best I've seen was a custom cab that allowed you to rotate the sections around to get different interfaces.
Looks classy as, but looking at that price I doubt it will gross sale one. Even if I had that much money, I wouldn't buy it. Is it worth hundreds? Yes. But someone should really tell him he's dreaming for that set price.
Also it say it can run PSone? I doubt that. Even so, the games would be a pain to control.
At first I thought it was a supergun+screen+ arcade stick all in a wooden enclosure and was mildly interested, then I realized it was just an over priced laptop with a wooden shell. For this price you could get an ultimate pimped out Mame arcade cab built, probably two of them for that price, hell probably 3.
