I saw this listing a while ago. It doesn't qualify as a "cabinet" anyways. More along the lines of a "setup".
His reasoning is flawed, in that that he's referring to entire complete MAME machine packages which have LISTED for over $3000.00 on Ebay (listed mind you, not necessarily SOLD).
Furthermore, he's trying to equate his own offerings to these aforementioned listings, even though it doesn't even closely, in any means of the term, resmble resemble what he's referencing. What he was trying to do, and rather poorly at that, was pulling a "bait and hook".
Unfortunately for him, many of our more knowledgable members here caught wind of this "pinky ring car salesman" tripe he was spewing, and called him to the mat on it. Simple as that.
You can't have an open chassis monitor on a stool of Duplo blocks, and call that a cabinet. Not even a showcase cabinet. What he has is more appropriately labeled as "unfinished"
