Cutting Holes

The next step was to cut holes! I think the easiest way is to use chipboard and make templates for the power supply,  the original switch and psu power cord connector. Make sure you know which screw holes you're gonna use on the psu! This is pretty straightforward so I wont go into detail.

After you've finished with the templates (hopefully you have removed all the components from you computer! metal shavings ya know!) Mark out the locations where you're going to be cutting. Remember, its easier to remove more metal than it is to replace metal. Measure twice, cut once.

I was unpleasantly surprised to find that exactly where I wanted to mount my psu the manufacturer of the case had been considerate enough to drill some holes for ventilation. So much for a clean, professional looking job. I just did it anyway. I started to cut with my jigsaw, it promptly died, bummer. DREMEL TIME!! Anyways, the tool for this job is the jigsaw. Take it slow. After your done with the cutting, use the file or a dremel to take down the sharp edges.

Repeat the process for the power connector and psu switch on the rear of the case( keep these as close together as possible, those wires are short).

Drill the holes for you screws and mount the power supply ,power switch and power connector .Mount the power supply and the receptacle and the switch.
