ASRock 90PXG7R0-P0EAY100 4x4 BOX-4500U Mini PC

The ASRock 4x4 BOX-4500U is an embedded PC barebone designed for users who want serious processing power without sacrificing desk space. Built around the AMD Ryzen 5 4500U — a 6-core, 6-thread processor with integrated Radeon graphics — it handles productivity, light content creation, digital signage, and home-theater duties with ease. The chassis measures roughly four inches square, making it one of the most compact platforms available for a Ryzen 5 processor, and it can be VESA-mounted behind a display for a virtually invisible setup.

Connectivity is a standout feature. Two Gigabit Ethernet ports make the unit appealing for soft-router, firewall, or redundant-network scenarios, while built-in Wi-Fi 6 (802.11ax) ensures fast wireless throughput. Memory support tops out at 64GB across two DDR4 SO-DIMM slots, and storage options include M.2 PCIe/SATA and a 2.5-inch SATA bay, so you can configure the system to match your performance and capacity needs. Because this is a barebone kit, buyers should budget for RAM, a drive, and an operating system license on top of the unit price.
