SilverStone ALTA G1M @ TechPowerUp
 

The SilverStone Alta G1M aims to allow for a mATX board while also offering enough room to install a 360 mm radiator or potent air cooling setup alongside a long graphics card. Even so with its unique layout and compact shape, you should have no issues placing the chassis on your desk with the same footprint of much smaller cases out there.
