Hi everyone!
... Love this topic - so many creative ideas!
It took me a long time to develop a display system that I was happy with. I finally settled on using media storage shelves from Prepac (for CDs and DVDs). they are very reasonably priced and come in a variety of sizes and configurations. I gave up on bookshelves because the shelves are generally too deep to effectively display small items like cards.
I also use acrylic (plastic?) deck boxes, top-loaders and card stands for my antique cards (left of the TV). For the modern decks (on the right), I just put them directly on the card stands.
I hope I can inspire others as they have inspired me! ... If anyone wants more info about the hardware, let me know! Everything is available from Amazon!

PS. This week, some repairmen stopped by to look at my furnace. They saw my card display and were totally blown away! We ended up talking about card collecting for almost 45 minutes... long enough that they were late for their next service call!
