Introduced in 2004, the TJ04 has been a main stable of SilverStone's prestigious Temjin series of tower chassis. Its excellent original design needed only a few minor tweaks and improvements over the years to keep up with the demands of modern PC hardware. An important equation in keeping the TJ04 a popular choice among system builders was its understated and classic styling. So in designing the TJ04-E (Evolution), SilverStone engineers kept the exterior styling largely unchanged while vastly improving the internals.
