extension things? you mean motherboard standoffs? surely you didn't just screw the motherboard to the case...... does it still work? if so, consider yourself very lucky tbh
the standoffs are usually a brass/copper color, and they should come with every case
As for the cable routing, it looks ok tbh, you could get old of an old PSU cover to further hide the cables from the psu to where they go behind the case but it's not essential
