Connect three full-height, half-length PCIe cards to computers equipped with Thunderbolt 3 ports. While thin Mac, Windows, and Linux computers with Thunderbolt 3 ports have sufficient processing power, the onboard processing capabilities often fall short for many users (such as professionals in creative fields).
