This bundle pairs an ASRock B450M PRO4 R2.0 micro ATX motherboard with a Cooler Master MasterBox Q300L micro ATX computer case for a compact yet powerful system. The ASRock motherboard supports AMD Ryzen 2000, 3000 and 5000 series desktop processors and includes high-speed USB 3.2 Gen2 ports, PCIe Gen3 x4 M.2 slot for fast SSDs, and protective circuits for stable performance. It can handle up to DDR4 memory speeds. The Cooler Master Q300L case features a sleek, transparent acrylic side panel to showcase interior components. Its adjustable I/O panel, magnetic front dust filter, and ventilated panels allow flexible setup and airflow for cooling. Despite the micro ATX size, it fits standard ATX power supplies, 240mm radiators, and high-end 159mm CPU coolers and 360mm GPUs. There's also generous cable routing space behind the motherboard. With the ASRock motherboard's speed and the Cooler Master case's cooling and expansion flexibility in a space-saving form factor, this bundle makes an excellent foundation for a compact yet formidable gaming, streaming, or productivity PC build.
