Many of you are unfamiliar to the Mini DTX form factor, but who could blame you? The common retail form factors included ATX, Micro ATX and only recently has Mini ITX become such a hit amongst conventional DIY builders. For those who care, Mini DTX was originally announced by AMD in 2007, to act as the "middle man" between the tiny 17cmx17cm Mini ITX form factor and the not so small 30cmx24cm Micro ATX. The fact of the matter is that many users would've liked to build a compact machine that doesn't lack in the expansion/upgrade department.Let's face it, Micro ATX motherboards are not small. At best, they are just a few centimetres shorter than conventional ATX equipment. Consequently, your computer can only be a few centimetres shorter or a few centimetres narrower. Alternatively Mini ITX means you can have a very small machine but you'll be limited to having just one PCI/PCI-Express slot. What if you happen to want an alternative? Cue Mini DTX...The development of Mini DTX held a number of advantages. Aside the obvious advantages for the end user, Mini DTX should be cheap to produce (exactly six Mini DTX boards fit on a standard PCB panel) and unlike Intel's experiments with the BTX Form factor, AMD's design is backwards compatible with the ATX standard that we know and love.Three years on, we're proud to have in our labs a retail Mini DTX Motherboard.
