I started off with a Corsair 460x and have slowly been customizing it. I made accent pieces out of 1/4" clear Acrylic that go along the PSU shroud and along side the mother board on the right side. I added LED lighting to give them an edge lit effect along with a black and matte charcoal vinyl design and to a little more detail I scored through the vinyl to add some lit lines. I also wrapped the protruding part of the PSU shroud in matte charcoal vinyl to give it more interest along with trimming it so I could do a push/pull setup with my 360 radiator. For the cables, I used Phanteks extensions and moved the grey and white wires around to make a custom looking pattern. On the top of the case I made a vent cover out of 1/4" clear Acrylic and layered matte black, matte charcoal and frosted glass vinyl to give it a nice lighting effect and hiding the back of the fans. There are 1/4" spacers underneath the vent cover that allows the fans to exhaust the hot air.
