Abstract: Examples herein relate to faceplates with filters. In some examples, an apparatus can include a faceplate, where the faceplate includes a plurality of perforations through a thickness of the faceplate, a filter attached to the faceplate, and a magnet to generate a magnetic attraction force between the faceplate and the filter such that the filter is magnetically attached to the faceplate.

Abstract: In an example, an air filter system includes an air filter and a thermally conductive particulate sensor (TCPS). The TCPS includes a temperature sensor to measure a first temperature of the TCPS at a first time, measure a second temperature of the TCPS at a second time, and provide the measured first temperature and the measured second temperature to a controller. The controller to determine an actual rate of temperature change based on the measured first temperature and the measured second temperature, compare the actual rate of temperature change to a target rate of temperature change, and provide a notification when a difference between the actual rate of temperature change and the target rate of temperature change is greater than an accumulation threshold indicative of a threshold amount of particulate accumulation on the TCPS.

Abstract: In example implementations, a system board is provided. The system board includes a printed circuit board and an extended portion. The printed circuit board includes an electrical connection to a processor of a computing system. The extended portion is to redistribute power. The extended portion includes a connection to connect to a power supply unit and a plurality of power connections. The plurality of power connections are located along an edge of the extended portion to connect wiring to other components within the computing system and deliver power from the power supply unit to the other components.

Abstract: Some examples include an expansion card retention device, comprising a retaining arm and a retaining bracket. The retaining arm is rotatably attachable to a chassis and moveable between an open state and a closed state. The retaining arm is postionable along the expansion card and includes an interior face to provide multi-point support along a top edge of the expansion card. The retaining bracket is rotatably coupled to the retaining arm. The retaining bracket pivotable about a first axis at a first end of the retaining arm. The retaining bracket includes a contact surface to engage with an interconnect bracket in the closed state. The retaining arm and retaining bracket are movable together between the open state and the closed state with a single user controlled operation.
