ZOTAC, at its Computex 2017 booth, showed off the ZBOX MA551 compact desktop with an AMD socket AM4 motherboard inside. Currently, this desktop is being displayed with a 7th generation A-series "Bristol Ridge" APU, but the board is ready for upcoming Ryzen "Raven Ridge" APUs up to 65W TDP, which combine a "Zen" CCX (quad-core complex) with a "Vega" based integrated GPU.

We took a peek under its hood, which reveals a custom-design motherboard, with an air cooling solution over the APU. The board also features a 2.5-inch drive bay with SATA back-plane, a 32 Gb/s M.2-2280 slot, an M.2-2240, an additional mPCIe slot (probably for the WLAN card). Two DDR4 SO-DIMM slots hold on to up to 32 GB of dual-channel memory. Other connectivity includes six USB 3.0 ports (including a type-C), an SD/micro-SD card reader, gigabit Ethernet, 802.11ac + Bluetooth 4.2 WLAN, and display outputs that include HDMI 2.0 and DisplayPort 1.2 outputs.
