Bit-Tech published a review of Hiper's Osiris chassis

Despite being decent value and having a wonderful alloy construction, there are a few faults that drag the Osiris back down to the underworld. The lack of a removable motherboard tray is certainly one, and while we admit that only those that frequently change their hardware consistently benefit from them, the initial build process is always made significantly easier by their inclusion.

Another is the lack of any extra cooling options, with just the standard three 120mm fan mounts included, not to mention the poor noise levels of the included fans. We never expected the Osiris to run silent, but we still want our cases to be as quiet as possible, and as we've seen previously, extra fan mounts or inbuilt fan controllers can help make up for this.

Despite these faults, we still do really like the Osiris. The one hundred percent alloy construction, removable hard drive cage and impressive thermal performance are all major plus points, and just by handling the case you get a feel for the brilliant build quality of the product. If only it was quieter and had room for a few extra fans and larger motherboards, the Osiris could have been something really special. As it stands, this is still a fine case and at this price still deserves your consideration.
