To assemble a powerful PC you no longer need an oversized desktop chassis. With a mini-ITX motherboard and Intel Haswell processor you can build a powerful yet compact PC capable of running any game. We tested a total of 13 Haswell ITX boards.
Even a powerful CPU such as the Core i7 4770K will work fine in a smaller chassis. Since so many features, previously reserved for expansion cards, are now integrated into the motherboard, you really only need one expansion slot for the graphics card. Companies such as Cooler Master, Bitfenix and others have Mini-ITX chassis that can fit both a heavy-duty power supply and one long dual-slot video card. More importantly, there are finally ITX boards with overclocking features rivalling those of Micro-ATX and ATX models. The huge full-size ATX boards have become obsolete for most users. A small mini-ITX board is plenty for a powerful all-in-one or game PC.
