Nice collection. I really see why you want those UGC cases. I guess they have to be modded for NES cases, right? That's going to be a pain for you.
I like your shelving, too. Is that a full shelf or just below your computer desk?
Yea... it will be a pain.. but I have until later this year to sit around and dread it! Yay backorder!
Thanks for the compliment on my shelves! Actually, my father and I built three 96 inch shelves above my computer desk (with about a foot and a half or so height).
Although, I'm a crazy Disney collector so I have snowglobes on the next shelve up and plush/collectibles on the top shelf. The bottom shelf is DS/GBA/GCN.
The Xbox 360/Wii are in the entertainment center. My NES games are under the entertainment center (moved them since the pic), N64 and Genesis are in a cabinet type thing in my closet. And my Xbox/PS1/PS2 are in one of those lock-up Video cases. It has three main shelves inside, and little shelve things on the doors.
I also have the custom spines/covers that Doom made for me but I didn't have them on in the pic. I have them in my "cover binder"

And to Doom, I have a scanner but I don't get the greatest scans... I'll try, but I'm not sure how they will come out. I have a HP Photosmart C5280 All-in-One and I can't find that desaturize option thing that you mentioned in your guide.
Xanderboy - the cardboard sleeves are shorter so it may be harder to make something out of it.
