The Corsair Carbide Series Air 540 is a mid-tower case which is designed to provide maximum airflow across your mainboard components. The Air 540`s dimensions are 415mm x 332mm x 458mm which actually make the case cube shaped. The Corsair Air 540`s two compartments are separated by a motherboard tray. The left side which is used to house all the components that attach to your motherboard as well as three pre-installed 140mm fans (two for intake and one for exhaust) and two Hot Swappable bottom mounted 3.5/2.5HDD/SSD caddies. The right side behind the motherboard tray has plenty of room for cable management it will also accommodate up to a 200mm Power Supply has a removable 4 bay SSD tray and will hold up to 2 5.25 drives. This is not where the versatility ends by removing the front 140mm fans the Carbide Series Air 540 can hold up to a 360mm radiator as well as a 240mm radiator at the top. The Air 540 is constructed of steel and plastic and much to our surprise it was not very heavy even with a full build./"
