well sir i think the only thing i could possibly suggest in the whole thing is casters for the bottom.. I've gone thru a couple small rubber maid "tool shed" builds before and it was always much nicer at the end with casters on the bottom... maybe I'm just ADD and have to move things around a lot...
anyways.. rock awesome case still
cant wait till i hear what you decide for a medium... in my opinion those little spherical grow rocks made from expanded clay and net pots with a dwc was always my favorite.. but you say under 18 in..... /shrug... let me know how it goes please
EDIT: PS... my apologies on the name... it was given to me a while ago by a friend of mine... its 13 characters long and works for many video games, its
never already taken :-)
