The Rosewill Orbit-Z1 has quite the interesting design, with the body being pretty understated, while the front panel draws all the attention. It consists of clean edges and 45° angles. There are multiple white elements which allow for light to shine through around and in front of the panel.
As the chassis lacks external drive bays, Rosewill has opted for a solid front cover. There is a line with a little wiggle in the middle, going down the center of the front. In the rear, things look a lot more traditional with the PSU bay at the bottom of the chassis.
The Orbit-Z1 comes with a windowed side panel. This one is quite traditional as well, using a metal cover and acrylic panel. While most brands try to stuff as much glass as possible into their cases these days, there is no real reason for the Orbit-Z1 to get such a costly upgrade. The only downside with the window are the visible mounting points, which do disturb the look a little bit. The opposite side is completely solid, but has been beveled outward to give you more room to route cables within.
Taking a closer look at the front, it is made of sturdy plastic all around. The little square loops in the center add a nice little design element to the chassis, especially as the whole line will light up nicely once the build is finished.
In the rear, the PSU bay on the bottom is pretty standard with its two sets of mounting holes for utmost flexibility. Above that are the seven expansion slots. Rosewill chose to go with break-out covers you can't reuse, which is unfortunate as it may leave you with ugly openings over time. The very top slot is already open, so you will have to use the separately provided cover here since most PCIe slots on modern motherboards tend to line up with the second cover these days. In the very top is a 120 mm fan with clear blades, white rubber pads, and RGB LEDs. It may be moved vertically to have it align with your CPU cooler for the best-possible cooling performance.
In the top, you will find another 120 mm fan protected by a magnetic dust filter. This unit is identical to the one in the rear, which means you get the same lighting elements here. The I/O on the Rosewill Orbit-Z1 is actually quite extensive and consists of two USB 3.0 ports, a single USB 2.0 variant, and the usual audio plugs. On top of that are the power and HDD activity LEDs and a power button. However, Rosewill has also added two individual fan controllers to the left, and there's a button with which to switch LED colors as well. You will also notice the gap in the front panel. This is due to the fact that any fans in the front will be installed between the chassis frame and front panel.
You may pull off the front of the chassis to reveal the aforementioned mounting spots for fans. You may install up to three 120 mm units here. Taking a quick peek at the underside of the Orbit-Z1, you will find a simple dust filter for the PSU's fan opening and four rubber-covered feet there.
