hrm.. a roomy case and 20" tall. Sorry, but you might have to "give an inch" as it were

. The only roomy ones i can find are usually no less than 21" tall.
Here is a cool suggestion for ya though, why dont ya chop the top off your sonata and hinge it so it opens like the hood of a car or something. I mean, if ya mod it right you'll have the "ease of use" your looking for, and im sure you can pull it off without it looking all ghetto and stuff.
It would be a cool little project, and it might save ya some cash in the end.
