A Look Inisde
Getting inside the A1 Plus is quite easy since the side panel comes right off. Inside there isn’t a whole lot of space, but you do have room for a mini-ITX motherboard and 2-slot graphics card. There is a power supply pre-installed, which is an In Win 650W 80PLUS unit. In Win has installed a plastic cover over it to sort of hide it. The unit offers three SATA power connectors, dual 8-pin PCI-Express connectors, 24-pin ATX power connection, and 8-pin EPS connector.
Looking at the small motherboard tray there are a few cable routing holes, which should make connecting things easier. At the bottom corner of the case is another In Win ASL120 RGB fan. With its orientation the airflow of the case comes in from the bottom of the case and is exhausted out the back and front of the case. Sadly if you want optimal airflow you’ll need to provide the two intake fans on the bottom of the case as they do not come included.
Opening the other side of the case we can see how the rest of the case is laid out.
On the backside of the motherboard tray are two 2.5-inch drive trays. These are removed by a single screw. If your mini-ITX board has an M.2 slot and with these two trays the In Win A1 Plus can support up to three storage devices. At the top left of the case is where the power supply is installed. We can see that the actual power extension cable is already connected, which is nice as in some cases it is not.
