I bought a CAT5 crimp device and a pack of connectors and coloured latches and make my own to the correct length.
Does push the eyesight to the extreme though :-)
As for the miscreant HDMI cbale though, there is ver little space above and below the socket but nothing in the same level . I might try a 90 degree adaptor which is cable-tied to the Mboard if there is space.
OTOH The mboard and Win7 Pro 32 will be 7 years old in June so I might start to think about what its replacement will be.
