"the V21 has two very important characteristics, the ability to rearrange most of its interior and exterior and the overwhelming cooling potential. The first one may not be something many users will choose to use since the horizontal positioning of the mainboard is already ideal for the size of the V21 but the 2nd one is certain to appeal not only to gamers and enthusiasts but even professionals since the ability to use up to 5 radiators and/or 11 fans is something we don’t see even in towers 3-4 times the size. And then there’s the stackable design, almost tool-less design, the 6 drive trays, 5 PCI expansion slots which can be used with cards up to 350mm in length, room for up to 185mm tall CPU coolers and space for up to 200mm long PSUs. Can you ask for anything more from a mATX/mITX PC Case?"
