Out of the box, the SilverStone SETA H1 looks quite understated and simple with a flat mesh front and gently angled right side for an added element of depth.
The entire front panel is made out of a unique looking mesh panel with the company logo in the top-left corner. It looks nice but feels prone to denting easily as it is all flat. That angled offset is due to cable management room behind the motherboard tray. As such, there is no need for venting here. In the rear, the enclosure features a traditional tower layout with the PSU bay on the bottom and the motherboard upright.
The main side panel of the SETA H1 is a clean glass panel hinged and held in place by magnets, while the opposite side is completely solid, using a pair of captive thumb screws to securely keep it in place.
You may pull the front off to reveal the ARGB LED strip inserted into the cover with two gentle bends. A diffusing plate has also been placed fairly far away from it to bend the light towards the front. Behind the cover are the two 160 mm fans, which are nearly the same size as classic 140 mm variants. As such, they will only fit into the interior of the chassis above the shroud. Both the removable, rotatable mounting plate in the front and the cutout in the inner metal shroud are too small to accommodate any other setup. While such unique fans are very nice, one has to wonder whether three 140 mm units out of the box would have been better.
In the rear, on the bottom, is the PSU bay with a single set of holes to dictate which way the PSU is installed. Above that are the seven horizontal and two vertical expansion slots. Seeing the latter makes a lot more sense over that same feature in the SETA Q1. In the very top is another 140 mm fan, this time set to push hot air out the back of the chassis.
The entire top is one big air vent that is protected by a magnetic, metal mesh dust filter. Removing it reveals elongated mounting holes for either three 120 or two 140 mm fans. The I/O is on the side of the top and consists of a pair of USB 3.0 Type A, one USB-C port and a combo audio jack. The tiny button may act as a reset or ARGB toggle switch. Being the size it is, pressing it is unnecessarily difficult. The SETA Q1 variant has a much larger button, for example.
On the underside of the SilverStone SETA H1 is a removable, fine mesh dust filter that may be pulled out the back for cleaning purposes.
