Upgrade ability also isn't an issue on the XL-Tank, with support for graphics cards up to 310mm and heatsinks 190mm in height, you should never run into a situation where the case will not work with your hardware. With the ability to house XL-ATX this case supports just about anything that is big. It also includes other neat features such as a removable hard disk drive bay and even offers support for up to six hard disk drives. Wire management with the XL-Tank is exceptional, given the mind numbing amount of holes in the motherboard tray to fish wires through.
