5" Mini-STX and Micro-STX Motherboards

Mini-STX motherboards, measuring 147 x 140 mm (5.8″ x 5.5″), provide a compact option larger than NUC (4″ x 4″) but smaller than Mini-ITX (6.7″ x 6.7″). Micro-STX motherboards extend this format to 147 x 188 mm (5.8″ x 7.4″) by adding an MXM slot for Mobile PCI Express graphics (MXM GPU) expansion cards, enabling enhanced graphics performance and machine learning acceleration. This makes Micro-STX ideal for applications in medical imaging and gaming.
