ok, not running entirely to plan but here goes
this will give you an idea of the size
first a point on ac ryan radgrillz:-
1. the stainless steel doesn't match lian li alu very well (I'm spraying it)
2. They tell you to drill the fan mounts out more but the steel is very very hard so you need a good drill bit. I also snapped several self tappers in it and had to drill one out which was a pita
3.the template doesn't quite match the swiftech triple so big holes are needed
Anyway, that may not be important to you.
I have a big problem however. The rad obviously overlaps the tray a bit and you are going to lose 2 pci slots depending on card length. My prob is that my sata ports stick out at the top left of the board so the lead is hitting the rad.
There are no fans attached there. My initial plan was to have the rad attached through the fanse to the case/grill but due to the sata ports it wont work. I have had to attache the rad direct to the case with the fans beneath it but i can only fit 2 fans as the third hits the sata's. even if the sata ports were not a problem It would still be very cramped. A thermochill would be really bad.
However, losing one fan should make the tubing really neat when I have finished and I am also having a 120.1 on the 120mm fan mount so still plenty of cooling in there.
I think If I were going to do it again, I would go with a double rad though. would be much easier.
