ASRock ConRoe1333-eSATA2

Conroe1333-eSATA2 is probably the best Asrock model, at least when talking about optionals. I'm not saying that it's not a decent performer (in fact the 945G chipset is pretty fast, especially when coupled with a good PCB and reliable capacitors) but what matters most is what it can do. For example, the box contains an optional module, which incorporates additional USB ports but also a Firewire header.
