At CES 2020, Razer unveiled the Tomahawk Gaming Desktop. It’s a compact PC with a modular design – that is, the internal components can easily be swapped out without having to completely open up the case and dig around.
To accomplish this, Razer is using a sled design with what looks like a miniature motherboard next to a power supply. But that mobo-looking piece is actually more akin to a GPU riser cable. In fact, the PC’s actual motherboard is contained within the compute unit, an Intel NUC 9 Extreme Compute Element. It’s a single box that looks a bit like a short and stocky graphics card, but that contains the mobo, CPU (configurable up to a Core-i9), RAM (up to 64GB), and storage (two M.2 slots). Next to the compute element, there’s a PCIe slot and space for a full sized graphics card, which can be configured up to an RTX 2080 Super.
