Hiper Osiris Mid-Tower Case Review

Interior Impressions cont.

One of the major critiques we had about Hiper’s first foray into the enclosure market was the lack of fans on their Anubis case. Sure, the mounting holes were there for a number of fans but unfortunately only a single 120mm fan was included. This time Hiper got it right by including not one but a trio of 120mm fans which leaves not a single fan mounting location for the consumer to populate. Each has a 3-pin fan connector but two of them can also be equipped with the included adaptors to attach them to the Molex connectors on your power supply.

All three fans are identical HA1225L12S 120mm units which are rated to operate at a constant speed of 1500RPM. After a little digging, I couldn’t find the exact manufacturer of these fans but the product number seems to trace back to a sleeve bearing Hong Sheng unit which is available at either 1200RPM or 2000RPM. It could be that this fan was custom designed for Hiper by Hong Sheng but I wouldn’t put much money on that assumption.


The motherboard tray is non-removable and has all the offset holes needed for ATX, Flex ATX, mATX and Micro ATX of which each is clearly labeled. However, if you were hoping for easy cable routing behind the motherboard, you are in for a nasty surprise since there is a small lip which prevents any cables from being passed where the sun don’t shine. However, there are other options for cable routing which we will discuss later.


Once the back panel is removed we can see that there are plenty of places to route cables behind both the motherboard tray and the main drive cage. There is an additional lateral support running the length of the Osiris and runs below the motherboard tray which once again blocks cables from being passed between the tray and the back panel. However, as you can see in the right hand picture above there is an indent where you can pass a cable or two.


The entire front panel is easily removed by firmly pulling on the bottom in order to reveal all of the drive bays plus the single removable 3.5” bay. In order to install any of the drives you have to remove the front panel but to be honest with you, it is a dream come true to be able to just pull the bottom and voila, instant access.
