With the extremely compact dimensions of the chassis, the case has a volume of just 7.25 litres - roughly the size of a shoebox or toaster. The fact that a complete gaming PC can be installed in it despite this size format is achieved by a well thought-out concept and a trick: The graphics card is housed in parallel behind the mini-ITX mainboard in a separate chamber and in total, almost every square centimetre inside the DAN Case A4-SFX V4.1 is used sensibly, whereas in normal tower cases there is usually unnecessarily much free space. A gaming PC can't be built smaller.
