i did oone pc, 100% custom cables and sleaved, not the perfect job, ( first pc ) and i took some time off ( it wears you down )
FINALLY starting my second ! i have had it, but the first one, seriously wore me out !
i know what you are going through !
just throwing in my 2cents !
you could always re drill and tap the holes ! ( this is what i plan on doing ) i have a g1/4 tap and drill bit ! you would need to take it apart however !
