One of my friends left over his The BESTMOTORing DVD's and I thought, I'm gonna use it and give him a cheap black DVD case. So I did and this is what it looks like.
Nice.
I use a 12 CD-box to store all discs related to Gran Turismo : GT1, GT2 (2 discs), GT3, GT Concept, GT 2004 Geneva promo disc and by the end of the week GT4.
I have a second box for other racing games and a third box for non-racing games. That's the only way I found not to carry 25 DVD cases everytime I go to friend's places.
I bought a greatest hits version back when my PS2 was trying to commet suicide. But back then I though it was my GT3 disc, but since the GT3 disc is defective. I burned it and kept the case.
