The cases were built buy a great guy over at hard forum. He's more than happy to make any custom modifications you may need and is constantly improving his design based on customer feed back.
At $120 a pop I couldn't be happier. The only other custom built cases I found like this were $300+. Even the build it yourself guide on this forum runs $100 and takes up an afternoon to build. (and with my build patience would come out lopsided looking like poo lol)
