Custom-built or pre-built systems are nothing new. They provide people who might not want to build their own system with a pretty awesome gaming system. For the most part they are built inside cases that are available to anyone building a PC, so there is nothing incredibly special about them. Enter the Corsair ONE, a 12L gaming PC with a liquid-cooled CPU and GPU, inside a case you are not going to find anywhere. This makes the Corsair ONE really unique and not something you could really build yourself. Corsair has been offering ONE gaming systems for a couple of years now, but today we are checking out the new i200, which features a Core i9-10900K, NVIDIA GeForce RTX 2080 Ti, 32GB of DDR4 memory, a 960GB M.2 NVMe SSD and more! Is this the ultimate gaming PC? Read on as we find out!
