I'm thinking shoe goo or hotglue around the wires atleast, or some kind of putty, anything that can mold into the uneven awkward gaps. I can't see sealing them up against dust or grit working any other way, and if they don't get completely sealed, and you seal up the other holes then I can see muck building up in there unable to escape, making things 10 times worse.
Meet in the middle, £50 posted? Half price of new is fair going rate for second hand and that would be £45
One brand new never used and fitted with Castle bullets and ready to go went for £40 posted earlier, so I think my offer is fair.
Just kinda Eager to get my spare Hyper ST Pro chassis running so I have something for family to have a go with to run along with mine.
