Having had a look at some of the reviews on newegg and other sites i've come up with a shortlist of:
CM Mystique 632S
Lan Li PC-A05B
Lan Li PCA17A
Ditched idea of Cosmos as read it got very hot and airflow wasn't great. Not sure if anyone could verify this.
If you have had 1st hand experience of any of the above cases i'd really appreciate some feedback.
