The case which is on it's way out is a silverstone TJ-05. I thought it was a safe purchace but didn't like it at all. The P180/2 which is the one I was looking at first is triple layered apparently and I am still considering it but the solo, which is smaller and so should fit better into the space is double layered so seems better overall.
The problem I have at the moment is that I need a smallish, quality case but as the quality and price goes up it gets increasing difficult to find one which is the right size and has decent airflow. The front runners at the moment are:
Antec SOLO
Antec 300
Compucase 6XR8
Others I am still considering:
Antec P180
Akasa Mirage 62
Silverstone KL02
I have a fair amount of money to spend on the right parts. For the case maybe £120 max but I would prefer to spend < £90.
