Silverstone KL01B Kublai Black ATX Mid-Tower CaseThe Kublai series performance tower chassis are made for computer enthusiasts that require a finely balanced system with cooling and quietness but without the extra features from the flagship Temjin series chassis. Constructed with steel body and aluminum front panel, the Kublai tower chassis retains the best qualities from both types of metal. The KL01 has a sleek front door that is designed and finely finished in the same method that follows SilverStone’s Temjin series.
