This product enhanced the appearance of 14 Ethernet cables to/from a 16-port switch in a rack. Sure, "empty 1U slot" would work, but it looks a lot better this way. While I don't have a full case fan, I assume this product also directs most of the air to where you want it rather than going through an empty slot.
