ARCTIC, known for its PC cooling solutions, has launched a new AMD Ryzen-powered PC that mounts under your desk and delivers silent operation, thanks to passive cooling. Called the Senza, this underdesk PC is not going to top the benchmark rankings, and that is not the idea behind this concept. The Senza is a daily workstation PC that allows you to free up space both on top and below your desk by not having a tower sitting next to you.
