U can get it off amazon, I got 24 pieces for about $38 bucks, just look up sound proof padding on amazon and pick the color u want and what shape size u want etc
I'm saving up for a 1080ti. Current rig: i7 6700k, 32gb ddr4 ram, asus sabertooth mobo, 1tb ssd, r9 290x 8gb video card. I just can't handle 4K and I don't have a 4K monitor yet.
