i used the 5.25 inch drive bay to house 4 hard drives expanding the capacty of my computer to 1200 gigabytes.
Step 1: I Knocked Off the Bottom Drive Chassis With a Cold Chisel
Step 2: Marked the Top of the Drive Bay Where I Will Drill the Mounting Holes
the i built a jig to fit the drive bay over for drilling on the drill press
Step 3: Drilled the Mounting Holes.
i used a drill press to more accuratly drill the holes
