DreamWare Computers posted a review on the SilverStone SG09 mATX Case
The desire of the ITX form factor is usually it's incredibly small size. Switching to an ITX sized motherboard can save you a lot of space and allow you to pack your computer into a very small and space saving case. With the right motherboard choice, you can even do the switch without losing any performance or functionality compared to mATX or full ATX systems - except for a few slots. ITX boards only have one expansion slot, meaning you can't run anything more than a single graphics card. Although you can still put a really high performing graphics card in the system to make a great gaming rig, the absence of any additional slots means that you could never upgrade to a dual graphics card setup, or add any other expansion cards that may be needed.SilverStone SG09 mATX Case Review
SilverStone, looking to show that with careful case design and component placement you can still have a near ITX sized case for an mATX system, has recently released their SG09 case. The SG09 comes from a long line-up of small form factor cases in SilverStone's Sugo series, and with such a small size it's going to prove that you don't need to abandon the mATX form factor if you want to go smaller!
