Duosonic held aloft the banner of DIY Mini HTPCs to break down old assumptions about large HTPC cases, freeing precious space in offices and living rooms where even the smallest square inch is dear. Its compact mini-ITX HTPC DS-M1 and DS-M2 case series feature an array of frames measuring 170mm x 170mm. The revolutionary frames were designed by geometry experts who understood that the dimensions of the frame impacted heat distribution -- knowing that an inefficient heat distribution system could result in severe losses of performance. Serious consideration was taken in positioning the hardware and cabling. Calculations for every aspect of the new cases were conducted by high precision professional computers to ensure heat within the case was effectively radiated, resulting in improved hardware performance. Additionally, both types of frames utilize special materials in their construction.
