But the Antec is also mATX, rather than mITX. In two dimensions it's pretty much exactly the same size - it's just the width where it's significantly bigger (in fact, I think you could stack two A4-SFX side by side and they'd be about the same size as the Aria).
But the A4-SFX is small even for an mITX case. There's a lot of mITX cases out there
bigger than the Aria. It makes a mockery of using an mITX rig to game, because most mITX gaming cases are big enough that they could've been designed to take mATX motherboards!
You know me CAT - I'm a huge fan of small computers. So it does my head in when people design huge cases for SFF components...
EDIT: hopefully the AMD/Intel collaboration will mean we start to get more *properly* small gaming PCs
