So what do you guys think? I think this is a very good PC given the price. I see the point of the CPU, Case, RAM, etc. EXCEPT THE PSU!! The PSU is a VERY LOW Quality! It is In tier 5! See:http://www.xtremesystems.org/forum [...] p?t=108088I would think that they would have used at least a PP&C 610 or a Corsair 520HX. My heart just dropped when I saw the PSU. .
I agree that they could have gotten a different CPU but, given the budget limit I see why they chose that CPU (QX9650) and the Motherboard, RAM, HDDs, Liquid cooling, etc. I still can't get over the fact that they used such a low quality PSU. I think Toms should check out the link above when buying a PSU for a guide.

I think that particular model limps up to Tier-4, but still I don't know anyone of the many people here I'd consider knowing what they're doing recommending or buying a Coolermaster PSU.

Actually, Coolermaster PSU's starting at 850W and up are manufactured by Enhance, which is a very high end OEM manufacturer (Tier 2 on that particular list). I know you looked at that PSU Tier list, but you should search a little bit more for reviews and recommendations because you would find that it performs very well and comes highly recommended.

That said, since they're trying to spend $4,000, I don't see why they wouldn't just grab a 1000W+ model for the 'futurer-proofing' and improved lifespand/efficiency of the PSU (running at lower % loads = most efficient, longer life). I would've grabbed 8Gb of RAM also, but /shrug I'm more interested in the lower budget ranges.

I have to agree with the PSU comment. With an extra 600 bucks to blow, there's no reason to have gone with that particular PSU. In addition, I was kind of expecting 1066 ram to push the limits of overclocking this system, especially with the watercooling setup.

Those things aside, at least this build makes a lot more sense than the previous two...

Although the PSU is actually made by Enhance, the PCB design is of lower quality than most of the other ones. I say Tier 3/2 at max.

It was the only power supply they had on hand with cables long enough to reach the CPU 12V power connector. They didn't choose the Coolermaster, it "chose them". The one they were supposed to use simply wouldn't work.

I'm not sure I completely understood their radiators. I get the dual fan one in the top, but did they use the other one because it holds the reservoir? And does it blow OUT of those side vents? Was it just me, or was that part of the guide confusing?

They said the cords in the modular PSU they used in their last high-end system were too short. They still could have picked out a better PSU that's out on the market.

Thanks for clearing this up. No wonder they "got" that PSU.

Yes, it probably should have been explained in the article a little better, but the photos help:
1. The top radiator sits above two exhaust fans, so it's always at the temperature of the inside of the case (which is still much cooler than the CPU).
2. The front radiator sits behind an intake fan, so it gets down close to the temperature of the outside of the case.

Water goes from the CPU to the top radiator where it's cooled to case temperature, then to the bottom radiator where it's cooled even more, before returning to the CPU. Reasons for that design include:

1. The fact that there was no "cold" place to put the big radiator and the small one wouldn't offer the performance they wanted by itself
2. The small radiator has a reservior, so they didn't need to drill holes and waste space for a separate reservoir.

Good points, but I don't think anyone had time to grab another unit, or several new units to find another one with long enough cables. Besides, hardly anyone really needs 1000W, Tripple SLI systems rarely exceed 700W and good power supplies have 50-150W of extra power beyond their rating.

8GB would have been useless using a 32-bit OS, which they picked for compatibility.

Wow that case is beautiful! It's so simple and concise, yet so elegant. DAMN YOU TOM"S HARDWARE now I must get it!!

i dont like the sound card...

^Hey, it came with the motherboard, imo. it is better than the normal usual on board sound.

true.... but if they had $4000 to spend, then might as well get a high end one...
