Neoseeker tried the Raidmax Narwhal Case
A quote from the article:
Back in March Raidmax introduced another new design to its extensive line up of computer cases, the Narwhal. This is a mid-tower case with pricing to match. Employing a sleek design, the Narwhal presents a robust business front with four external drive bay openings and an easily removable front air filter grill.Raidmax Narwhal Case Review @ Neoseeker
Along with the front removable air filter, the Narwhal also incorporates removable top and bottom air filters which should help keep the interior free of dirt and dust. The side of the case has a small window with a raised honeycomb-style pattern on the inner side of the plastic pane that is not geometrical in shape, so when viewing through the window you get a slightly distorted view of the case interior.
Inside the case you can remove the middle HDD drive bay, allowing for installation of video cards measuring up to 430mm in length. The bottom HDD drive bay has three drive trays that have mounting points for 3.5? drives (held in place by slightly bending the plastic trays with pins in the side rails, then inserting the drive) or 2.5? SSD drives by using screws to mount the drive in the middle of the tray.
