and how would you go about finding such a place.. i mean are there businesses out there that do nothing but powder coating?

Actually I took 2 coin doors w/frames in and had them both done that way. For the 2 doors and the 4 coin chutes it was $80. I felt it was worth that to have a nice looking and durable finish on my coin door.

There is a powder coating place I used to see on my way home from work. I just stopped in one day and talked to them and looked at the various colors and finishes they had to offer. I'm sure you could google them for your area.

It is just a powder coating place. They do everything from motorcycle wheel and frame to race car frames and everything in between. The nice thing about the powder coating is you can just about hit it with a hammer and it won't chip. It's very durable.

I have this terrible fear that after aquiring a pc for MAME spending some £££ on it hours tinkering and updating id blow it up by doing this so USB sounds a bit of a safer option! :laugh:

Its not that bad and you probably wont be using all the connectors anyway oh and its all color coded!

CheffoJeffo:
I would think that you have a greater chance of fouling things up hacking a thin little USB cable that was never really designed for that purpose, as opposed to using the existing power connectors that were designed specifically to deliver the required power more than adequately.

Sorry, but HOW THE HELL would you screw up getting power from the power supply if you can wire the rest of your cab?!   :dunno

The connector is a 4 pin molex.  The blacks are ground.  The red is +5v.  The yellow is +12v.  If you need a 12v connection, use the yellow + black.  If you need 5v, use red + black.  If you need 7v, use red + yellow.  The polarity (+/-) is just which side you put the ground on (one way is +5v, the other is -5v).  This is the easiest part of the project IMO.  If you can't do this, you shouldn't be messing inside a cabinet anyway.

OTOH, if you hack a USB you have to worry about stripping the wire without cutting other conductors.  Then you have to figure out which wire is what (5v, ground, Data+, Data-).  If you screw this up, you might actually do some damage to the PC or minimally the USB port.  If you screw up the other hack, you potentially short the PSU BUT you would have to be a retard to do that IMO.

For reference, I've done both hacks.  I find the PSU version MUCH easier and far less prone to problems.  Also, the wires in a USB cable aren't really that good for connecting to since they aren't that big (~24 gage I guess) whereas PSU cables are usually much bigger (~20 gage or so?).
