A Closer Look Around

The Cooler Master Praetorian 730 incorporates an all aluminum chassis fitted with an open mesh front panel and sculptured aluminum front door.  One of the original Wave Master’s weaknesses was poor airflow into the chassis thru the front panel.  The new Praetorian 730 door design fixes that problem and provides for much better airflow.  There is also better clearance behind the closed door for accessory bay devices like fan speed controllers that have knobs and/or buttons that stick out the front.

The Power-On button, Reset button, and indicator lights are mounted across the front of the case at the top edge for easy access. 

The 730 chassis has openings for four exposed 5.25′ drives and two exposed 3.5′ drives (along with four internal 3.5′ drive bays).  The door opens to the right and has a sturdy feel thanks to solid hinges and a feather-touch latch that doesn’t rattle when the door is closed.

The external I/O panel is located on top of the 730 case under a pop-up panel and includes the following ports.

Near the bottom of the front panel, behind the mesh grill is a 120mm case fan with blue LED lights that shine thru and provide subtle accent lighting even when the door is closed.

The grill section in front of the fan can be easily popped off and includes a thin dust filter that can be washed.   While the low speed fan was relatively quiet, it did produce more motor noise than I would expect, which over time could be annoying.

Both side panels on the Praetorian 730 are removable but the top panel is not. The left side panel has a large ventilation port and a fixed shroud inside to help direct cool room air to the main processor heatsink fan area.  A clear acrylic ‘splat’ design accentuates the vent from the outside.

The shroud position is not adjustable so it may or may not line up with your particular HSF.  An optional 120mm case fan can be mounted inside the side panel instead of the fan shroud for increased airflow if desired.

The right side panel is solid and does not include any vent holes.  Removing it however provides access to the ‘back-side’ of the case, which offers a lot of space behind the drive bays for tidying up and hiding wiring.

Moving around to the rear of the case we see a pretty typical ATX layout. A standard power supply slides in from the back and is held in place by an external mounting plate.  Below the power supply is the removable motherboard tray, which includes two blue LED 80mm exhaust fans.

Looking at the bottom of the case, we see two audio component style feet at the rear and two support columns with rubber feet in the front.
