A very good Micro-ATX case, optimised fo

The PC-A41B is an all aluminium case geared towards water-cooled systems. The layout for air-cooled systems is less than optimal.

The PSU can be mounted in one of two positions depending on whether the system will be air or water cooled. With a water cooled system the radiator is mounted under the top of the case, but only one fan is supplied - although a blanked off second fan vent is provided. The PSU mounts vertically off the rear of the case, positioned above the CPU, and would impede access to the cooling block.

With an air cooled system the PSU is located at the top of the case in the conventional position, and the only exhaust fan is in the centre of the top panel. Since there is no rear fan a tower cooler is best mounted vertically, which then fires hot air directly into the PSU air intake - the top case fan is some way forward. The warm air from the CPU will heat up the PSU more than it would have done if a tower cooler could have been mounted horizontally with extraction performed by a rear case fan. By modding the case, a 60cm fan could be positioned where the PSU would fit in a water cooled system - this would improve the airflow around the VRM's, and may allow a horizontal installation of a tower cooler. If the user is prepared to accept a less elegant solution an 80mm fan could be installed in the same position.

The motherboard tray has only three cut-outs - a large one by the PSU for the PSU cables; the main cable entry hole between the drive trays; and a smaller one for the EATX12V cable. There are no cut-outs at the bottom of the board. It is possible to cut more, but note that the bottom edge of the board is very close the bottom of the case which gives enough room for all the usual cables and connectors except for a USB3.0 header connector which is too thick to pass by the case side flange and the bottom of the motherboard.

There is plenty of room behind the motherboard tray for cable management, and if additional cable cut-outs are made an extremely neat installation can be achieved. It is advisable to use 1mm grommet strip on the edges of all panels through which cables pass - some edges are quite sharp.

Three 120mm fans are provided; two at the front and a top fan, referred to above. The three fans are ball-bearing types and are fairly quiet, even at maximum speed. When correctly set up in the BIOS, and under normal load usage, they are barely audible above the background noise - even with the PC sitting on the desk. The application of acoustic foam lining would make the system even quieter.

The front fans are provided with removable filters which very effectively prevent dust from entering the case which, depending upon how the fans are setup, is helped by the positive pressurisation. There is also a filter on the bottom of the case covering a grille which appears to be redundant, at least in a positive pressure system - this filter could be used as a spare.
