I've posted about my system in other threads, but here's another photo of it. I use regular plastic bins and clear plastic video game boxes. These cost about $1 apiece. I find that the Atari 2600 game box size works for most ISA & PCI sound cards, and the Intellivision game box size works for slightly larger cards such as your SB Pro CT1600 and AWE64. I use a pink antistatic bag, which makes visually identifying the card a little easier than it would be through a smoke-color antistatic bag. Additionally, I put a little sticker on the box spine that lists the make/model. For longer cards (PAS, Soundscape, etc.), I use the hard plastic cases that you see at one end of the bin.
I have one bin for sound cards and one for video cards. I probably need one more bin though.
I've used this system for a couple of years now and am quite happy with it.
