Riser 1U5R2
1,5U height PCI riser card which changes the insert direction of two slots by 90 degrees. This riser card does not expand a PCI slot into two PCI slots. Both full PCI slots must be present on motherboard. It is targeted for systems that may require two full height PCI slots in 1,5U height chasiss (DS16 for example) but uses mainboard that has two and more PCI slots on board.
