We’ve seen arcade machines encased in a coffee table, a briefcase and an old barrel. Redditor Uhohthommo’s uncle went for the industrial look and stored his arcade machine’s hardware inside a 200L (approx. 53gal) oil drum. It has two sets of controls and has 60 games built in. Redditors surmise that Uhohthommo’s uncle used a PCB like this one to run the machine.
Perhaps it’s just the angle with which the shots were taken, but it seems like you’ll need either really long arms, a really low chair or a neck brace to play on this machine. It looks sturdy as hell though.
