"The functionality of the Core V21 is – I’m not even sure there’s a word for it – dizzying? Unparalleled? I was able to relocate a 240mm radiator and fans from the top of a horizontal motherboard tray, flip the case on its side to a more traditional vertical orientation, and replace the Corsair H100i in a top exhaust location in a few seconds."
