To achieve this, the bottom five of a total of seven slot brackets on the Lian Li PC-O11 Dynamic XL will be removed and replaced by those included in the kit. Those wishing to install a second graphics card, also in a vertical orientation, will require a second riser cable which is also available from Lian Li.
