Let me clarify... Is it possible and within the rules of the game being played? If the answer is yes, the losing party is just that, the loser. After all... GAME. Back to the monopoly statement. One player can easily dominate the other players, if the other players are getting mad about losing and flipping the board and quitting. They're the asshole, not the dominating player. Change monopoly with any game ever. Still a game. Be butthurt all you want to, flip my board and I'll not be inviting you for another game. Beat me, oh well, I lost, life goes on.
If you don't like a game with rules that enable. Then don't play it. And certainly don't try to cry about it... Admit it's not the game for you instead of being the asshole that complains that the game isn't fair.
For a workstation, go with the path of least budget impact. Building won't save you much. Could probably find a full on all in one meeting the specs they need. Photo/Video editing is a high ram hog, the more the better.
Edit: The machine I linked is tiny as well. only 14" tall, 6.7" wide, and 13.4" depth. Would tuck nicely out of the way, out of sight, out of mind.
