The IW-BM648 is a mini-ITX system case from InWin, a well-known maker of simple and practical products such as the BT, BL and BK series for micro-ATX mainboards. The new BM series is designed for mini-ITX and includes models that differ with the design of the front panel.
The IW-BM648 looks kind of stocky after the two previous flat system cases. It is considerably taller but shorter and narrower. Like with the Foxconn case, the front panel is made from glossy plastic (this is going to look nice and appropriate next to a glossy monitor). The I/O ports are hidden, and the neat white strip, ending in vent openings, makes this system case quite good-looking.
Hidden below the cover, there are two USB ports and two audio connectors. We just don’t get it why are they so close to each other if there is a lot of room nearby?
The Power and Reset buttons are fitted nicely into the design: the Power button ends the white strip on the front panel, being located under its edge. And the Reset button is hidden below the silvery square. Two activity indicators reside nearby.
There is an 80mm fan on one of the narrow side panels. Another, smaller, fan can be glimpsed through the vent grid nearby. This is not some special cooling system. The power supply is just located near the front panel in this system case.
The IW-BM648 can be placed flat or upright as is indicated by the round pressed-out spots for feet on the side panels.
The feet are small circles made from some rubber-like material with a sticky base.
You can only see a power connector but not a power supply at the back panel. The vent grid confirms that there is no power supply here. There are two expansion slot brackets (not reusable) with external card fasteners. The system case supports low-profile cards only.
