After many years faithful service, my old coolermaster case has now been replaced.
BeQuiet Silent Base 800 now houses my aging kit. It is a bit on the huge size and I still have some work to do getting USB 3 on the case fully functional (no connector on motherboard) , and a fancy fan controller to control the 3 supplied fans (only one 3 pin fan power connector on motherboard).
The Coolermaster has now been relegated back to housing the spare kit.
