nothing special, likely just some random cabinet that someone has modified with that car door of a control panel. It LOOKS like a factory quality but I can't see any of the inside wiring or anything...but someone probably bought an ipac and went nuts with some buttons and aluminum sticks or something.
and typically xarcade with their cabinets they are selling just plotz their tabletop arcade stick (like the xtank or whatever) panels right on top like an afterthought. (kinda lazy IMO) this one you got has an actual flat control panel, so someone took the time to make it. (google xarcade cabinet and you'll see what i mean about the control panel) so I don't THINK it's xarcade....the components are similar to what are available on the slicksticks, so it's possible someone robbed all the parts out of the slickstick and installed them into this cabinet.

but all those parts are typical parts sold as "mame arcade" type things (spinner, small trackball, etc) the panel is somewhat disproportionately sized with a bunch of empty space at the front curve of the panel, so someone made the panel work with the cabinet...not changing the cabinet to fit a more appropriately sized and designed panel. so i'm kinda thinking this cabinet is someones kit.
it looks like nothing standard... besides you can't just walk into a place and say "yeah gimme a control panel overlay for a dynamo arcade cabinet" in this world, everything is custom. those buttons can be placed anywhere... the cabinet, any shape height, width, depth.
but i guess, if you want more info about what you got there.... the button layout it's a 2 row by 3 button layout, a fairly typical "stick fighter layout". with low medium high punch on one row and a low medium high kick on the next. (street fighter etc) it's kind of modified in the sense that the odd button to the lower left is what makes it a modified layout... it's to emulate a "neo-geo layout" wich has 4 buttons in a row (the odd button and the lower row of the 2x6) typically used on neo-geo games and used with your index, middle,ring and pinky fingers each controlling a button. it's not a 100% neo-geo, since they've moved the button to cram them up next to the stick due to the trackball being there... but not totally horrible. it's probably the most popular kind of layout giving you pretty comfortable and convenient controls for about 90% of the games out there you might play on a mame machine.
all the rest are going to be administration buttons and could be anything... whoever made this would know... and could be programmed for....well...anything.
monitor is a wells gardner D9200 a decent enough monitor. it's limited to 640x480@60hz resolution. as long as you take care of it and keep an eye on it's capacitors and switch them out at the first signs of swelling, it will last quite a while. if the capacitors go and the monitor is allowed to continue to run, it will grenade itself with 100 blown components and be nearly impossible to fix without special equipment and piles of time and money.
over all if you like it and you didn't soak a pile of money into it... hey, it's yours! so do with it what you want make new panels and artwork and stuff for it. There is all kinds of ideas here. take a peek through the projects. if it WAS a pile of cash and you were looking to restore it to original as an investment or show piece.... theres nothing really to restore it to... just a generic arcade box with some wires and buttons. It's not rare or super popular or anything. if it was somewhere in the middle.
in any case, y'all can do whatever you want to with it.
