MSI A320M PRO-VD Motherboard ($60 US):

The MSI A320M PRO-VD is a very basic M-ATX motherboard that comes with a simple design. The board features a 3+1 phase PWM. The socket is powered by a single 8-pin connector. The motherboard comes in a brown colored PCB so we can tell this would be at the entry level side of things. Memory options will include two DDR4 DIMM slots that can support up to 32 GB of DRAM. Expansion slots include a single PCIe 3.0 x16 and dual PCIe 3.0 x1 slots. Storage options include four SATA III 6 Gb/s ports and a single USB 3.0 front panel connector.
