The FanlessVC2300S is a passively cooled computer that measures 360 x 303 x 130mm (14.2″ x 11.9″ x 1.2″) and has an internal volume of 14.2 liters. But what makes the system impressive is that it has a massive copper heat sink to help keep the system cool without the use of fans. In fact, the computer is constructed so that the heat sink is actually a big part of the chassis. While you’d think there’s room inside the case for a larger mainboard, keep in mind that cooling system uses up a lot of the interior space. Cooling features include17 x 8mm heat pipes1 x 10mm heat pipe3 x aluminum heat sinksThe system is said to be able to dissipate up to 250 watts.
