This is one of the coolest advertisements I've ever seen:
You can see the motion tracking and compositing is a little weak in places, but even so, it's still pretty amazing.
Also, here's a link to the breakdown: http://vimeo.com/69175471

While on the topic of blender, here's my latest creation:
It's still a work in progress, the texturing still needs a good bit of work, but I'm pretty happy with the exhaust flames, just a few more tweaks and they'll be pretty good.
Usually smoke or fire takes a really long time to bake, and then renders pretty fast.
With the adaptive domain, I've been able to compute the smoke pretty fast too; it took less than a minute and a half to compute 200 frames at 128 divisions and high resolution set to 2.

If you want to carry your keys neatly, there are two good options that I know of:
Now I just can't make up my mind!
Maybe I should put frequently used keys on a Switchy, and keep the rest on a KeySmart...
Kickstarter has some really neat products.

Here are the specifications:
CPU: 2X Intel L5420 quad core @ 2.5 GHZ
SATA trays: 4, but make sure the seller includes them.
USB ports: 4 USB 2.0, 2 front, 2 back
Ethernet: 2X GBE + one for management
Video: Internal Intel chipset, 1X VGA (back)
Memory: Up to 16 GB DDR2 EEC
This is an incredible value. If you are going to build a renderfarm or compute cluster, it doesn't get any better than this. If you find a better deal, I want to see it!
It has a PCI-E slot, so you can add a better graphics card. It's single slot, so the maximum you could fit would probably be something like a GTX 640 (Though that starts to approach the cost of the server!) If you want more GPU power in something like this, you would probably have to go to liquid cooling.
If you like this model, but need more memory, the
I noted 16 GB maximum memory for the -SC model above, but I forget, it could be 24 GB.
Before getting this, I read some of the reviews (which are surprisingly scarce), and it was claimed to be loud. This is not the case. The fans spin up loudly, but once booted, they throttle down, and stay nice and quiet. I've got a Dell laptop right here that is louder than the server. The server also runs very cool, so the cooling is doing its job. I ran a smoke simulation in Blender for an hour, all cores at 100%, and it only got mildly warm. This was in a room with an ambient temperature of probably about 85 F.
If you're curious about how fast this is, here's a nice comparison chart: http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+L5420+%40+2.50GHz&id=1259&cpuCount=2 This shows that it's a little slower than a modern desktop, but remember that the entire thing costs somewhere around half of what just the CPU of a new computer might cost! At the cost, scaling out over multiple servers is a good option too.
I've run Linux mint, FreeNAS, and Ubuntu Studio on it. Boot time is rather slow, but I haven't timed it. When using onboard graphics the X server sometimes has to be started manually with startx. I haven't had any such problems with a graphics card.
All in all though, if you're looking for power without the price, it doesn't get any better than this!

This is good advertising, at least in concept. The video is somewhat sub-par.
I guess this reduces the possibility of a leaking liquid cooling system ruining your motherboard/CPU.
My first thought is that the coating will trap heat, but I guess some silicone based coatings have decent thermal transfer.
Now I'm just waiting to hear of this for laptop motherboards!
