I've come across a great opportunity to make my very own custom acrylic case , and I've started getting ideas and measurements together from the ATX form factors. I still have a couple of questions tho. 1) What needs to be grounded in the case? A friend suggested that the back plate would need to be grounded. True ? 2) What would be the best fan arrangement? I'm considering stealing the C3 ideas - ie 2 80mm intake fans by the HDD's, one 80mm output at the back, and a 120mm blowhole on top. Any better ideas? Also any suggestions / tips would be greatly appreciated! Thanks!
