Amazon offers the MSI B350M Gaming Pro AM4 Micro ATX Motherboard for $69.99 with free shipping. (Newegg charges a couple bucks more.) That's the best price we could find by $10. This VR-ready motherboard features support for AMD Ryzen and 7th-generation A-series/Athlon processors and includes one PCIe 3.0x16 slot, two PCIe 2.0 slots, and four SATA connectors.
