Introduction and Case Exterior
The Define Mini C is the micro-ATX variant in Fractal Design's excellent Define series, and this compact chassis is nearly as small as some of the mini-ITX cases we've looked at in recent months. The advantages of micro-ATX for a small form-factor build are undeniable, including added expansion slots (and multi-GPU support), and more robust power delivery for greater CPU flexibility including AMD socket AM3/AM3+ support.
I freely admit to being a small form-factor enthusiast myself, and as much as I like mini-ITX, there are times when micro-ATX just makes sense. I mentioned AMD compatibility above, but even if you're building with Intel there are reasons to consider mATX. One of these is Intel's enthusiast platform, as X99 requires at least a micro-ATX board for quad-channel memory and greater PCIe flexibility. (Naturally, at least one mITX X99 board is available, but this is limited to a pair of memory slots and - of course - has just one PCIe slot.)
As soon as I unpacked the Define Mini C, I knew it would make a perfect home for the EVGA X99 Micro2 motherboard I had on hand. This micro-ATX board makes a compelling argument for the smaller form-factor, as very little is lost vs. full ATX. The Mini C (which sounds like the name of a mini-ITX product, but Fractal's mITX variant is the called Nano S - which I reviewed a few months back) should make a great home for a powerful compact system. Let's get started!
