And on I went about measuring (twice!) and cutting (once!) the appropriate amount of AcoustiPak material:
After cutting out the correct proportions, I continued to firmly place the material in the desired locations. Some areas of suggestion are across from the CPU, parallel to hard drives and fans, and on the sides and roof of your PC's case.
Finally, I carefully inserted the foam blocks into their appropriate slots: two underneath the DVD-RW drive and one above the 3.5" cathode switchboard. The foam blocks are already cut into their correct sizes and are by far the easiest part of the installation.
With the accompaniment of three foam blocks and an entire sheet of AcoustiPak Deluxe inside your PC, you're unfortunately only half way there. On this specific test-bench machine (sporting a Lian-Li PC-75B case), one side panel is taken up by a Plexiglas window; thus making it illogical to place the AcoustiPak material over it from the inside. Left was a past heavily vibrating PC only partially covered with sound-dampening material but supposedly virtually completely 'proofed' from inner vibration.
