The Core series by Thermaltake launched with the E-ATX full tower Core V71 last year. Since then, Thermaltake has expanded into the mid-tower (V31, V41, V51) and mini-ITX (V1) form factors. The Core V21 that Benchmark Reviews will take a look at today rounds out Thermaltake’s lineup with their first micro-ATX Core offering. At first glance, the Core V21 shares many design similarities with the other Core chassis. As is true with many things in life, looks can be deceiving as the V21 is the first Core chassis to officially offer a multitude of motherboard orientations. While it arrives in stock format with a horizontal motherboard layout, it can be transformed in a matter of seconds to a traditional or inverted layout. We’ll see how this works as we build a system inside the Core V21 over the next few pages.
