Just look at the thing, the metal look cheap and thin, the brushed finish is inconsistent AT BEST, the ports were clearly soldered onto a generic pcb and then stuck in there, no thought put into it (on the side, metal tabs are visible, just "there") and the disproportionate casing (on the edges of the side door) are extremely annoying.
This isn't a quality computer imo, its a low quality product with decent specs for the price and a niche selling point (the TEC). If engineering, quality and design matter more to you than price, go open a Mac Pro and tell me that you aren't impressed. I wish I could afford one.
Now that I have completed my rant, I'd like to clarify what the TEC is for everyone who doesn't know (seems like quite a few). A TEC (Thermal Electric Cooler or Peltier Chip) is essentially a small, ceramic square that accepts an electric current, making one side of the chip get extremely hot and the other extremely cold. The better you sink the hot side, the colder the other gets. Conversely, if you give it heat, it will generate current. When you sandwich this on top of the CPU (cold side down) and put a waterblock on the top side, you essentially get an electric only sub-0 (theoretical) cooler. That is basically what their block does. Really nice job on DS' part for this, I must say. If you are interested in the technology, the Cooler Master V10 is a TEC + Air cooling, and there is a forum here on OCN just for TEC stuff.

I'd really just swap the case out for an 800D. Seems like a simple solution to a problem that really isn't a problem.

As far as macbooks go, I was always impressed aesthetically. Loved the feel, the overall weight and the screen was gorgeous - only problem is that it's way too overpriced.

I'm a bit interested in knowing how they drive the peltier?
I can't see if there's an extra PSU anywhere. I wouldn't drive a peltier, from a normal switching PSU like we have in our machines.
Back in the day we would normally try to have a minimum of 25amps, on a dedicated linear psu, for the peltier alone.
Even though they're using the 1500W Silverstone PSU, I would still not load an entire rail with just one device. And it's continuous load as well.

Furthermore the peltier units are usually 15 or 24V ones, which also takes the Silverstone out of the equation, as you'd want to feed it with around 14V for a 15V unit, and around 17V (and higher) for a 24V unit.

Anyway, the system looks really well built. So I'm sure they've taken everything into consideration. I just can't find any specs or hints of an extra PSU. So as I said, I'm just interested in seeing how they've done it. it's great to see TEC getting back in the game. I'm still amazed that they can cool the hotside of a peltier, with aircooling today hehe.

Anyways good luck with your quest to get a Nehalem powered $5000 rig with a single Radeon 5770 rolleyes.gif

You should both look at this system:

http://www.insanelymac.com/forum/index.php?showtopic=277433

YES, you can not only out school the top of the line Mac Pro in price, but also in speed... So it can be done and when you want to play games all you have to do is just use your other SSD or HD and install your copy of Windows and you'll have two operating systems in one. BTW, the actual total cost in the end was around $4,200 for a Dual Xeon X5690 CPU setup with a EVGA 580 GTX 3GB GPU. It can be done.

Also, it seems that (for the most part), posters here just wanting the CryoTec CPU Waterblock and nothing else. Well, that will set you back some as that cost's $1,200 for just that CryoTec unit alone. Not worth it to me. Plus you can't get it anyway as you have to purchase that with one of their systems (which would cost you even more for them to build it). They win on both ends. Now if they were to allow you to purchase this CryoTec unit separately, they could easily bring the price down to about $600 to $700, then that would be more palatable for more consumers. Especially since we're in a global financial mess anyway (that we're not getting out of anytime soon - if ever). Heck you can get a Phase Cooler for around $350 (used) on eBay. Maybe even lower, so why would you pay $900+ for this CryoTec unit? Sure you may not want a literal freezer sitting by your system making that typical sound that a refrigerator makes, but who cares, right? What ?!?! wth.gif I can't hear you from all the noise this refrigerator is making !!! Awesome !!! thumb.gif Here's a perfect system example of what I'm talking about:

http://www.youtube.com/watch?v=-I5cFABm4rM&feature=plcp

Lastly, let's say you do go with getting a Digital Storm Online (DSO) setup just so you can buy this exclusive CryoTec unit (that's made ONLY for a DSO system), to eek out about 10% (maybe a percent or two more) more CPU performance for an extra $1,200 using this CryoTec unit (Plus, all the other parts that DSO is going to charge you more for to set up this system), is it really worth it?... I personally think with all the amazing systems that I've seen that others have personally built here on Overclock.net and other forum websites, we can all build similar systems ourselves that are on the same level as what DSO, MainGear.com & other online PC building companies out there are trying to sell it more for, that we could do for less $$$ on our own... cool.gif

I think they're probably using a 200W TEC. They're also only running it at 12V and not the recommended 15.6V. If memory serves it's not a linear decrease in power consumption when you don't run at Vmax so it's possible the TEC only draws 150W. No biggie for a 1500W psu. TEC's are cool and all but really it makes more sense to use an evaporator-condenser setup.
