The PS05 came well packed with two foam ends and the case itself wrapped in plastic. Oddly the case instructions were missing, but these were easily obtained from SilverStone's website. My first impression was this is a minimalistic design. Visible on the front are four 5.25” bays and two 3.5” bays. There is no door covering the drive slots, though personally I view this as a plus. I have had more than one case door develop problems after a while, so I don't miss it at all.
Both side panels are featureless. Moving on to the rear of the case we can see the single 120mm exhaust fan along with the space for a bottom mounted PSU. I haven't seen many entry level cases with a bottom mounted PSU, so I was excited to see this. My personal preference is to have the PSU down by the ground as it makes wiring easier and lowers the center of gravity making the case more stable.
It is also important to note the two holes included here to pass tubing through the case for a water-cooling setup. The holes are small so you won't be able to fit large diameter tubing though, but smaller tubing should be fine. I do miss the side window, but this case is clearly not designed to sit on a desk but underneath, so a side window is really unnecessary and not every likes them. Behind the SilverStone logo on the front is a 120mm fan bay which we will look at later.
Also on the top we see the mesh vent with a filter covering a bay for two 120mm fans. The filter is removable so you can clean and reuse. The case is clearly meant to have a subdued presence under a desk with the top mounted ports and power buttons. On the bottom we can see the vent for the PSU fan and an additional 120mm fan slot.
