Vintage case, looks to be a pretty generic beige case from that late early 2000s era. Havent come across this style with the carry handle before, and looks pretty neat

In good overall condition as shown in the images, though there is a bend in one side panel. This is likely able to be bent out pretty easy but havent attempted this myself

Measures - 

480mm H (roughly, since it includes the handle) x 515mm L x 185mm W

Listing is for the case only, floppy drive, optical drive, and anything extra in the case are included as is, untested
