Visible from the rear of the Precision PS05B is the 120mm exhaust fan (the only fan that is pre-installed), seven expansion slots, and the ATX power supply mount at the bottom of the chassis.
Working our way inside the case the layout is rather basic yet effective. The design is not anything unique but rather common to many of SilverStone's lower-cost cases and those from other manufacturers. With the PS05B, there are also more plastic tool-free mechanisms than we are used to seeing on SilverStone cases, with the 5.25-inch and 3.5-inch drive bays being tool-free as well as the expansion slots. While we do not mind dealing with screws when installing components especially as we have more faith in them over some of the less reliable tool-free mechanisms made of cheap plastic that often break or do not secure the hardware well, with the PS05B everything seems to work just fine. Our only complaint with the tool-free options is with the expansion slots where that was a bit of a nuisance.
Fortunately, the internal 3.5-inch drive bays also support mounting 2.5-inch drives, which is good for those interested in building an SSD-based system. There are also two pre-cut holes in the rear of the chassis for those interested in water-cooling or to otherwise route cables inside. The PS05B should be capable of handling graphics cards up to about 280mm in length, which is suitable for most graphics cards except for some high-end options like the ATI Radeon HD 5970. The CPU cooler can be up to 160mm. While it does not matter much on the PS05 model without the side window, the inside of this chassis is painted entirely black.
