I havent checked the msy website but .......
The antec 300 is a great case with excellent cooling . Now its been replaced by the 300 two , and the budget spot is now fuilled by the Antec one
The one has front USB 3 ports and pretty good cooling still despite losing a front fan spot .
I'd want a mb with internal USB 3 headers .http://arc.com.au/pub.php?gid=23862&pid=44100&p=product
