Enjoyed reading the thread, great pics.
Cheers Mark, I'm glad you like it. I'm always worrying that there's too many pics.
Any updates on this Wolvers?
No bud, I've been pretty restrained recently!

I have, however, been considering where to go next. Top of the list is a NAS HDD upgrade as my current one is close to being full and I'd really like the DS710+ cos it's much faster than my DS210j.
Also, I was so impressed with the SSD RAID set up that I'm considering an SATAIII version!

I can't see much point upgrading to sandybridge right now and I feel there's enough GPU power in the two 5850s for now. TBH, I'm a bit disappointed that the 6950 is so long otherwise I'd have considered a pair of those. They might fit but it's a real pain. I think I'll wait and see what the next gen brings.
The main aim is to improve the cooling power of the loop and reduce the restriction in the the loop to increase the flow rate.
I've machined a new lid plate to fit the fans and the rad to, just waiting now for some 90 degree fittings to arrive from OcUK so that I can work out the final orientation of the rad and get it plumbed in. I have a feeling this is going to be a really good mod, although quite a lot of work has gone into it so far and there's still lots to do including the final machining of the counterbored fixings for the lid plate.
