Launched under SilverStone Kublai series, KL03 is the latest case from this manufacturer, targeted to users that want a big case with high-end thermal performance but don't want to buy a very expensive all-aluminum product, like the cases from Temjin series also from SilverStone. In fact KL03 is a hybrid product: its body is made of zinc-coated steel, but its frontal panel is made of aluminum.
