Sounds like you need a man room. One room that is your domain. Beyond the door which your word is law.
My uncle has one. He decided it was the best way to keep his wife and sanity. He decorates it, the computer is in there along with the HAM radio and his other items. Basically. his play room.
My aunt has the rest of the house. Which she decorates and accessorizes to no end.
Maybe get some nice shelves to display them on or get/make your own custom boxes.
