The case that can hold a full size DVD isn't really the be-all and end-all it might seem to be. The games all fit on mini-DVD. Blank mini-DVD-R media isn't priced outrageously enough to make an upper case pay off at the present outlandish price people are asking for the case half. I think I bought 5 10 disk cakeboxes of blank Ritek 8cm DVD-R in 2003, and 2 remain unopened, around 30 discs at a price difference of no more than 50 cents. I got a translucent purple full disk case top with flashing blue lights that proved to be useless in both senses. The best thing about it is that its color remained stable while the Nintendo indigo plastic on the rest of the case discolored. I'll sell it on eBay for the outrageous price people are getting for them if I ever run across the original upper case I put somewhere safe 16 years ago. I recall something from back then to the effect that the DVD drive in the GameCube may be a little short on radial travel to actually read all the way to the outer edge of a full size DVD. I don't find anything about that on a quick search, but maybe that's because it doesn't matter for 1.4GB backups.
