I tested this using a Kill-A-Watt meter and three Dell P2210s. The results were 56W showing google.com on all three, and 59W showing blackle.com on all three.
I think your facts are out of date. The latest SSDs beat hard drives in every category, sequential reads/writes and random reads/writes. SSD random write performance has been superior to the fastest hard drives for quite a while now. Performance is even better with TRIM and 4K alignment in Windows 7. It is sequential write performance that has typically been weak, but even that is no longer the case.
As for the emergency brake, it doesn't take a whole lot to overpower one of those. In my manual transmission car (which has over 300hp) I forgot the brake on once and was able to get going with no problem. It did make a horrible screeching noise though.
Its not quite that easy to add more space. RAIDZ and RAIDZ2 pools don't support expansion yet, so you have to be using mirroring to achieve expandability. And when you are using mirroring you have to add 2 more drives to expand an existing pool. Even when using mirroring I don't think you can remove drives like you say.
The Hitachi is a 2 platter drive, model HDT722525DLA380. Both of the drives in question are mounted using 5.25 to 3.5 adapters, near the top of the case, with no fans on them. Hitachi is on the bottom, WD above it, optical drive above that. The drive cage in the case, which does have a fan on it, is full with other drives.

I have the 1TB GP model and I have a hard time believing that it uses significantly less power than my 250GB Hitachi drive. It consistently runs hotter than the Hitachi. I thought maybe the sensor was wrong but it feels hotter to the touch too. As of right now my Hitachi is at 42 C, WD is at 44 C. It has hit 50 C before, while the Hitachi peaks around 46 C.
I quite enjoyed doing kamikaze jeep runs in early versions of BF1942. If you hit a tank just right with a jeep going full speed it would explode. It was the most effective way to eliminate a tank. They 'fixed' this is later versions though.

I've had the same email address for 11 years, although I probably wouldn't notice if a real email came through since I use it as a spam dump for the last 5 years or so.
At my university we had to register the MAC address of our network card with the IT department when we signed the AUP. Unregistered MACs were not given an IP or routed to the Internet. I don't recall if there was anything in the AUP about being responsible for what other people did while using your PC, but even if there was I think setting a OS password would be considered secure enough by their standards. As others have said, this would not prevent someone else from using your PC with bootable portable media, and given that your roommate could provide someone else access to your PC without your knowledge or consent I don't see how you could be held responsible in a lawsuit.
I don't think anyone really needs 1000W in a desktop, but with quad core CPUs, SLI video cards and multiple hard drives 500/600W isn't unreasonable.
And to answer the grandparent, a higher capacity power supply could use more power if the efficiency at low loads is worse than the lower capacity power supply (and it usually is). A typical modern desktop system at idle will only use around 75W of power. Let's say the 400W is 75% efficient at 75W load and the 1000W is 70% at the same load. The 400W will pull 100W from the wall and the 1000W will pull 107W, so 7W of power will be wasted.
I've never heard anyone complain about.jpg images at 90 quality, demanding lossless versions of the same image, except for people who use the image as source material in other productions, yet for some reason it's cool to pretend to hear things that aren't there. I think the same reason applies to audio. People want to use the files for 'other productions' (burning CDs).
Search for 'Quiet and Cool' for AMD and 'Speedstep' for Intel. All Athlon 64s support Q&C. I don't know the status of Speedstep in Intel CPUs. The motherboard has to support Q&C also so you'll want to confirm that if you are purchasing one but I think most do.
I think your numbers are a little low. My Celeron 566 with an old low-powered AGP card, 2 sticks of memory, 2 network cards and 1 hard drive takes about 80W idle. My watercooled A64 X2 with a 7900GT and 6 hard drives takes about 200W when idle.

Oops, got my logic reversed in that second sentence..
The brakes almost couldn't stop the car with that much power.
Car and Driver tested the ability for brakes to overcome the power on the engine. In a 540hp Mustang they found that it nearly could. http://www.caranddriver.com/features/09q4/how_to_deal_with_unintended_acceleration-tech_dept

My HTPC is quieter and uses less power than the DVR I had rented from my cable company.
CPU makers don't list the power that their CPUs actually consume. They list the Thermal Design Power, which is a bit different.

That show was awesome. I was just watching it on DVD last night, "The Melty Man Cometh".

Most google apps haven't progressed much since the first version.

I am using a Kill-A-Watt power meter. The X2 is overclocked and Cool'n'Quiet is not enabled because it causes problems on an overclocked CPU.

I agree, using hard drives is stupid. He can't be much of a geek if SSD wasn't the first thing that came to mind when planning this trip.
Motorola phones are picky about the power source though. My Motorola phone won't charge from my Blackberry charger.
Where I work every programmer is on salary and gets two 19" monitors. The lucky ones get two 19" LCDs.
There are several thousand forms actually, those are just some of the more common ones.
