looks ugly/ rip off from stacker.. esp the rear.. if you wanna make compartment for exhaust fan, then choose one la. i know it gives some variety in choosing but the vent gills restricts too much air. summore which ever mode you choose, you'll get extra vent holes not occupied.

if its 1k, the it's better buy off purchasing a cheap casing. any how, by the looks its not an alu casing

just my 2 cent
