A major update after all - half year without change proved too much for me

1) In: 2x GTX 580 3GB with EK-FC5X0 GW Acetal Nickel blocks in series
Out: 3x GTX 480 1.5GB in parallel
I won't bother with 3rd this time since it won't work in 3D surround anyway and dropping £500 for the benchmarks only doesn't appeal to me now.
I reckon that following benefits:
a) 480 to 512 cores
b) hopefully higher (~950-1000mhz) OC - with GF110 being better OC as well as more power available by dropping 1 card
c) more VRAM
d) full 16/16 slots (from 16/8/8)
should provide better performance in my 3D Surround games.

2) In: 2x Koolance PMP-450S (D5 Strong) 24V pumps with Koolance 12V-->24V converters
Out: 2x Koolance PMP-400 (DDC 3.25 - 1 DIA)

I'm going to reuse EK Dual D5 Single Loop top.
Having done some homework on the PMP-450S, I'm going to run it at 18-20V. This hopefully should be fine in this top and all in all provide much better flow than 2xDDC 3.25.
RPM sensors from both pumps will go into Aquaero for monitoring.

3) In: 12GB (3x4GB) RAM - Patriot Viper II Sector 7, 1600mhz @ CL7
Out: 6gb (3x2GB) RAM - Corsair Dominator 1600mhz @ CL7

Nothing against Corsair, just need more RAM for video editing in Vegas and I prefer to have 3 sticks rather than 6...

4) In: All fans controlled by single CPU header on the mobo (PWM signal only)
Out: Currently only 6 fans controlled that way, rest running at full speed all the time.

All parts have been ordered and should arrive no later than Friday - so expect some eye candy this weekend and next week
