Hiper Osiris case
The case opens easily, with some very high end latches, and even the fingers on the bottom are spring mounted and articulated. The window is EMI proof, it has a a mesh screen over the plexiglass, and there are fan mounts galore, tool free everything. Osiris even a slight mobo standoff to route cables around. Because both sides of the case have an easy open latched door, this is actually usable.

Another interesting post from The Inq shows that Hiper is working on a new case called the Osiris that great cable management and air flow enhancements as well as hinged doors on both sides.
