Installing the motherboard is done using screws and spacers. Several of the spacers have edges to hold the motherboard in position as it is screwed down. There is plenty of space above the top and forward-facing edge of the board, while the openings in the shroud are well-placed for keeping the visible cable mess to a minimum. With ATX boards, you will have to move the covers over a little bit to give you the room you need to route cables through the grommet-covered holes to the side of the motherboard. The SilverStone SETA H1 should easily be able to house any GPU you can throw at it with the fans in the front since there is ample room even with the Gigabyte RX 6600 Eagle.
Adding an SSD to the build is done by detaching the plate, installing the drive, and putting it back by securing the whole thing with a thumb screw. When installing a drive on the internal cover, the steps are essentially the same.
To add a 3.5" drive, first detach the cage and pull it out from underneath the shroud. Doing so reveals two possible placements for the cage if in need of additional room for the PSU. Each drive rests on screws with rubber rings, which hold it in place securely. Once filled, simply slide the whole cage back into place and secure it with a thumb screw.
Lastly, installing the PSU is pretty straightforward. There is lots of room to get it in and out of the shroud even with cables routed through to connect things like the front audio or fans. As you can see, you could throw all but the most extreme power supplies at the SETA H1.
Adding any AIO in the ceiling is done using classic screws. As SilverStone had provided their PF120 AIO for a past review, we went ahead and used it in the SETA H1. Alternatively, you may install an AIO of up to 360 mm into the front and top of the case, which we have also tried out, of course, but since the SETA H1 comes with two pre-installed fans in the front, we chose the ceiling instead. Thanks to the offset mounting holes, there is lots of space between the motherboard and AIO—you won't have to worry about any hardware colliding with it. A big AIO may even slot in above the rear fan, maximizing the whole area for cooling.
With everything installed, the interior and backside of the SilverStone SETA H1 make an excellent, clean impression. Thanks to the many hooks for zip ties and well-placed, grommet-covered openings, keeping things nice and tidy is easily done. The special steel covers in the interior also help a little bit. If using an SSI form factor motherboard, you will still have horizontal openings that are currently covered to wire cables through, thus making the H1 uniquely capable of tidy setups even in that scenario.
Finished Looks
With the system turned on, the ARGB strip in the front lights up alongside a white LED underneath the power button. The fans are rather noticeable even in idle. This bodes well for cooling, but at the cost of a better balance between idle noise vs. temperatures.
Looking at the front, you can see how the ARGB strip bounces light off the diffuser bar. It is visible but not as bright as direct lighting, and the flow is broken up by the support structure behind the metal mesh cover. The clean glass window gives you a nice view of all your cool hardware as there is no tint, and everything in the rear is where you would expect it in a modern ATX enclosure.
Looking through the top, you can see the ARGB lighting from your components, which is a good sign for airflow.
The SilverStone supplied ARGB controller can be wired up to the reset button to toggle through several animations as well as a set of solid colors you may feast your eyes upon below.
