just top. was lucky and bought it here for about 9 euros (some time ago). laptop fits perfectly pure (wide), depth about 2 cm free which is pretty good because it is not too tight and thus is rauszunehmen easier. that's very good side compartment to stow there a 2.5 "or two of them + cable or other utensils.
just recommended. very good product. now 1 year in use and neither solved seam or something happens. very robust. mfg
