Ahoy there and welcome aboard.
Nothing against you selling whatever you wish (within reason, ha ha!). Whether you choose to place it in the arcade or non-arcade section is up to you.
One thing I will say, if only to temper any expectations is that this is a vintage/original arcade forum, where the majority of posts are about original cabs. That said there is a mame section and modern repro/scratch builds feature every now and then. (I have one for instance).
Where you may be disappointed is if you hope to recover some vast sums of money you may have spent on this when purchased. Typically GreedBay is often a better audience for these type of cabs, but you never know unless you try.
Good luck with the sale. Possibly think of posting a valuations thread first?
