I developed this because of working with computers and trying to keep everything together, the motherboards are from VIA Technologies and they are like the Raspberry but far more powerful - getting up to 64-bit on a 1.0GHz QuadCore processor, which is enough to run any operating system This is for mounting a Pico-ITX motherboard, with a HDD slot underneath, IDE HDD on the side and mounting space for additional bits from the motherboard header pins, etc I have included the AutoCad files if anybody wants to modify it to their requirements, Or send me an email and your requirements if you want it changing go to www.marlowenterprises.com for more information
