When I use braid I use a staple gun and staple it securely to the inside of the cabinet so there is no slack or loose cable hanging around. Exactly the same method they use in Pinballs for the last 30 years..... |

I have mine mounted to wood also, but since it isn't grounded i'm getting hum in the audio. Searching led me to this: http://forum.arcadecontrols.com/index.php?topic=89559.0 which basically indicates wiring to the PSU gets rid of the hum and grounds the motherboard...probably a good idea regardless of the hum. |

Exactly how do you go about wiring from the PSU to the motherboard? Did you just tape the wire to the side of the PSU case or use one of the screwholes? I'm getting a hum in my audio when I plug my amp into the mobo and this might help solve it. |

usually this is not nessary, when it comes to cases it's more a matter of safety then anything. having the case grounded means if there is a short it is shunted to ground.. so when you touch it you dont get zapped. it's normally not nessary to ground to the PSU, however if you feel it nessary it wont hurt. what i would get is a small nut+bolt, put it though a mounting hole and wrap a wire around said bolt then tighten it down. 18-22ga wire should do the trick. for the psu just wrap the other end around a screw and tighten it down on one of it's mounting holes. no need to crack open the PSU because it's housing is grounded. again not usually necessary but it certainly wont hurt. |
