Then I started before G.A.S., it was one camera and lens in the small cabinet beside the bed. With G.A.S. I added plastic drawer with four sections. Like one of those from Walmart. Later on it migrated to regular dress drawer from Ikea. Now with G.A.S. maintained at get one camera, get rid of one camera level I have two vertical cabinets from old media center. It is cheap, not even Ikea and it was giving to us for free because TV sets are flat now.
I have two similar cabinets. Bottom half is two doors. Upper part is with glass doors and shelves. And top is another two small doors storage. Those cabinets are not wide, half-meter deep and wide. In glass areas I have all of my cameras. I'm keeping it under ten or dozen cameras and same amount of lenses. One lower storage at one cabinet is for darkroom paper. Another cabinet similar storage is for caps, less used lenses, flashes and so on. One upper part is for bulk film loaders with film. And same part in another cabinet is for cleaning stuff (blower, paper and so on). Between these two cabinets I have small table with PC screen, film/prints scanner and inkjet printer, plus two speakers and PC on the floor shelf. At some point I'll re-connect two upper shelves connecting two cabinets (my wife removed them after moving cabinets and table around same room) It will give space for photo books, inkjet paper and albums, boxes with prints.
