Wow, that looks like a really nice case.
They've placed the PSU at the bottom, gotten rid of the door form the Anubis, kept the easy-open latches for the sides panels and appear to have kept the all-aluminum super-strong chassis.
"The case is made entirely of 6063-T5 military spec alloy, which Hiper tells us offers outstanding heat dissipation. The easily detachable side panels are 3mm thick and one of them as an EMI proof window so you can see your PC's shiny (or dusty) insides at work.
Hiper's description of the case reads:
"Osiris defines a design level of its own, not only regarding the unique look and feel. The whole case is constructed for tool-less assembly with an innovative airflow concept as the ultimate cooling solution: The PSU is located at the bottom with a direct fresh air intake, so the heat of the PSU is isolated from the case completely. On the top and on the back there are 120mm fans with 3pin plugs for connecting with the motherboard. And, just like Anubis, the modular HDD rack has the third 120mm fan on the front. Moreover three PCI air ventilation plates are also included in the package; this provides better exhaust capability for systems equipped with SLI or Crossfire. Of course Osiris supports XL ATX PSUs and all graphic cards currently available."
The edges of the buttons, plugs and the front side are diamond laser cut and the front USB and eSATA ports are placed on the front top side of the case for added convenience.
OSIRIS will be available in brushed black or brushed silver finishes and carries a recommended retail price of €129 +."
