dknight writes "I have an extremely large media collection. Probably 1500 DVDs and 400-500 Blu Ray discs. While I love having such a large collection, it is so big that its impossible for me to find anything. I've finally decided that it may be worth my time to invest in buying or building some sort of automated storage/retrieval system, much like those tape robots. I assume buying one may be prohibitively expensive, but I do have access to lots of electronics components and some expertise. Am I better off buying? Building? How would you do it? If at all possible, I'd like to keep the media in its case while in storage, and have the device retrieve the case rather than just the disc."
