Ik heb 750GB (WD green) + 1TB eraan hangen.
8GB geheugen: Corsair XMS3 CMX8GX3M4B1333C9
Quad Kit van 4 identieke modules van 2GB dus 8GB in totaal.
DDR3 1333
voeding: be quiet! Pure Power L7 350W / be quiet! SFX Power 300 Watt
pricewatch: be quiet! SFX Power 300 Watt

If your focus is to get the lowest idle wattage possible.
Some thoughts:
- See if you can lower the core voltage of the CPU @ 1.6ghz lower than 0.84v
- If you lower the base clock of the HD3000 graphics, you should be able to drop the voltage
- Also there might be a bit of wattage in the RAM by lowering voltage
- If you want to get drastic, replace the 1TB desktop with a 750G laptop drive.
Looks good so far.
After watching the system a little more, 40W idle is pretty normal. Running a benchmark, it did touch upto 90W with all 4 cores active and 'accelerated'. For running through the Windows Update crap last night... I'd say the system was at idle speeds for roughly 97% of the time... so idle consumption will be key. With the good idle behavior of the 2500K, I'm assuming that the 'value' placed into the 2500T is that its 'energy management circuitry' is designed to stay under the 45W ceiling... while allowing a 1GHz Turbo (from 2.3GHz) ... and actually increased GPU turbo headroom (lower base... higher turbo... less EUs than a 'K').
The initial underclocking effort may be somewhat of a waste, since the processor does such a good job of power gating and underclocking itself. I'll look and see how low it can go be checking out the 2500T voltage specs... that should have some safely reduced voltages. The GPU was going to be my next target. I assume those also get power gated and reduced automatically, so finding a way to influence this will be interesting. RAM is already running at 1.5V (just at stock 1333 now). This box will eventually be a Home file Server, so I'll have 4 or 5 drives in it (which I already have) so dropping laptop drives won't be an option... although a good idea for a new build. I think it roughly works out that 1W turns into $1 if you run that device 24/7 for a year. The 40W idle will save me a ton compared to the old server that idled at over 80W.
