Installation
The internal layout of the Osiris chassis is pretty typical for a standard mid-tower ATX style case except the PSU is located at the bottom. The overall installation of basic components was accomplished with ease. As you will see in the following pictures there is plenty of room to work inside this enclosure.Power Supply

The power supply slides into position from inside the enclosure and is secured with four thumb screws thru the backside panel. Note: The opening in the bottom of the case underneath the power supply is designed for use with a PSU bottom intake fan.

Exposed Drive Bays – Optical Drives
The front bezel must be popped off before a 5.25” ODD or bay device can be mounted. Each drive just slides into position and is secured using four thumb screws to mount the drive. The upper two 5.25” drive bays come fitted with brushed aluminum covers, which work well with most but not all ODDs.

The Osiris enclosure comes with one 3.5” bay adapter mounted into a lower drive bay, which can be used to mount a fifth internal HDD or relocated up into an exposed 5.25” bay to mount an external card reader or other 3.5” bay device.
Internal Hard Disc Drives

The removable HDD cage (modular-rack) is secured with thumb screws and just slides out the front when released. The HDD cage is designed to mount up to four 3.5” drives and incorporates a 120mm cooling fan on the front. To mount a HDD you just slide it into position and secure it with the provided thumb screws. The drive cage incorporates eight rubber strips inside, which you would think would help isolate HDD noise/vibration but they don’t really line up with the installed drives.
ATX Motherboard

I installed a full size ATX motherboard (Asus P5N32-SLI Deluxe) into the Hiper Osiris enclosure without issues. The chassis uses threaded standoffs for mounting points and everything lined up and fit perfectly. As you can see in the photos there is a good bit of room around the motherboard area to work and connect cables.
