Heh, a dream room for a gamer for sure. Always interesting how American houses seem to use a lot of wood for construction, in the Netherlands or Germany we use bricks and concrete mostly. Your lay-out design doesn't seem to have the windows indicated.
The Windows... I never showed them on the original layout because they were to be covered for complete control over the lighting. Keep in mind one of my favorite games was Quake... the darker the better for that game.

The wood... actually my whole house is wood with a concrete slab. Brick and mortar is common here also, but it depends on where you are. Wood is very inexpensive here compared to some place I am told.
I updated the layout image with window indicators so it is easier to realize the image angles if desired.

I have been collecting games for about 20 years now... I am in my 40's and really ready to get my games a place they deserve. I have worked hard to get to this point and my passion for games and gaming has never really slowed down, so this is my tribute to my games.

Just like game development, I have more planned than I can ever put into this room if I ever want to get it finished, so I am going to set a time limit and do the best I can with that time. Otherwise it will take so long I will never finish anything... I am learning from the mistakes of 3D Realms with DNF.
I don't think any of us like having to drag out boxes just to see our games... and we probably all have had to at some point unless we were really lucky.
My intention is to get ALL of my games out on shelves front out, at all times. No more boxes, no more edge wear etc. I also want to get all of my systems out rather than having them out one or two at a time with cables all over etc. I will have out all my systems with all their controllers and peripherals or at least until I run out of space.

I don't have every system, but I do have Vic-20's, Commodore 64's, PS2, PS1, Nintendo 64, Super NES, NES, Sega Genesis, Sega Saturn, Atari Jaguar, Hyper-Scan, Retro-Duo and Family Boy (SNES/NES Modern Consoles), 30+ Handheld "Plug and Play" games, then most handhelds and several hybrid handhelds etc.
I am really excited now!
