Nice   
Just look into this site of the case comparison for cooling and quiet...and to my surprise, ah lian performs really well.

At first, I thought ah lian performs badly in terms of silence.

Really like ur suggestion for the dust filter. 
hmm...need to check where can I get the silverstone magnetic filter coz i think i like that solution.
Did u get ur case the silverstone magnetic filter or mod with plexi/glass? can share some pic 
Now im leaning towards the ah lian    ...just need to make sure if can make adjustment with little investment.

For a moment there, i was going for Fractal Design Define R4 instead of ah lian and some of the reason is because of ur comment and others regarding the 8pin hole and backside clearance here https://forum.lowyat.net/topic/1010313/+2320
Thanks for the input....really help me a lot.

got the magnetic filter from viewnet.

later bro. its a work rig used as a hackintosh. Will try to take a pic. But not going to that office until wed

hey that 8pin thing is doable. I manage to. Just a bit of tact on how to push it in.
