As elegant as that centred DC jack placement is for PCB size, it also makes the jack incompatible with the existing PCIe slots on almost any case: not only would it be blocked by the case rear panel, but it projects below the plane of the PCB the card would otherwise plug into, so the motherboard tray would prevent it from fitting. This is a problem if (for example) you want to use the adaptor to add a second card to an ITX board with an m.2 slot, and mount that in case like the NCase M1.
