Building a Green PC 190
Kermit writes "Ars Technica has put together a green DIY system building guide. The idea is to build a PC offering decent energy efficiency as well as solid performance. The 'Green Gaming Box' draws about 125W at full load (not including a monitor); the minimalist 'Extreme Green Box' uses a mini-ITX case and a VIA CPU-motherboard combo for about 30W at typical load. If you want to mix and match components, or modify your current system so that it uses less energy, there are plenty of options for swapping out individual components."

In truth it is just another catchy phrase to sell you yet a new computer. Buying a new computer does nature more harm than just keeping your old computer.

Lower energy usage. Recycled. Probably faster than the VIA. And you can beat a burglar to death with it.

The problem with costs today is that no long term costs are included in prices, copper mines that poison areas bigger than Los Angeles have no obligation to pay for what they destroy. The mining inudstry is very very dirty, they some are situated near natural reserves, which mean we are going to have to fix everything after they have shut down.
There are mines in Sweden that are still being cleaned up, 30 years after shutting down.

You can take a queue from data centers where power and heat are major issues. Instead of having a spinny whirly storage (or even solid state) on every PC, use NAS or SAN. If you've got to have 2nd - Nth PCs, use PXE, NFS and iSCSI for storage. Virtualization can help save power, too.

Low-power PCs are a good idea, sure, but we need our software to also be efficient. The two, together, could get us a long way toward truly 'green' computing.
And while I am ranting about bad software design...
AC-to-DC conversion is messy and lossy. Fortunately, we do have servers that can take DC directly from a shared AC-DC power supply. This concept needs to move into the home. Why should my PC, monitor, printer and God knows what else all each have their own AC-DC power converter box? Homes could have a single large converter and then have DC-only outlets for all those appliances that need it.

What you're saying is that if I have 20 marbles in a bag, and take two out, I still have 20 marbles in the bag. It's just not true.
All these little steps add up over the long run. Reducing your energy consumption by 3% might not seem like a huge difference, but if millions of people do it, it makes a difference. I recently measured how much power my computer rack uses, and found that I could cut usage by 25% through a few simple steps (like making sure the CRT I sometimes use on my firewall is powered down, setting the drives in my system to spin down after a certian amount of idle time, etc.) The whole thing (three computers, two monitors, various networking bits, laser printer) consumes 300 watts at idle. That 100 watts I save from shutting off the monitor adds up to 584 kW/h each year (if it's off 16 hours each day), which in my state keeps 7,475 pounds of CO2 out of the atmosphere, and saves me $97 in electricity annually. From only shutting off a monitor!
The shit adds up. Throwing your hands in the air because there's no one thing you can do that's a magic bullet for the energy problem is cynical and lazy.

This should be enough to save you quite some $$$ in your energy bill and polish up your green credentials.
For a more radical approach, consider getting a notebook instead of a desktop for your next upgrade: notebooks will, by design, consume less power than desktops.

I am sure some people here would be shocked, but I run a Duron 1.3 processor, with a Zalman fanless heatsink, and 768 MB of PC-133 memory. I run dual displays (CRTs) but they shut off after 5 minutes of inactivity. The machine is up all the time (current uptime is 70 days), so I am sure I am pulling some power. I live in AZ, and in the summer it get HOT in my office... so I rigged dryer hose to pipe the PS air out into my garage. (luckily, right next to my office) I installed a low-speed fan on the garage side to help pull the air. It made a very noticeable difference in the temperature in my office. My buddy was having issues with his P4 3.2 machine, and he just bought a new Dell. So he gave the old one to me. It turned out the video card was fried, and one of the PSU fans was dead. Instead of buying a new PSU, I just hard-wired the fan on the PSU to run off of one of the 5v connections. In my area, you can put out your bulk trash once a month. I saw one of my neighbors put out a PC... I thought I could scavenge it for parts. Upon getting it home, I found out it was a fully working Sempron 3200 system! It only had a 30GB HDD and 256 RAM, but was fully working. So now I have two fully working PCs sitting here. I'll probably replace my Linux machine (Duron) with the P4, and my dusty Windows machine (Athlon 900 slot!) with the Sempron, after buying a memory upgrade.
It just amazes me what people are willing to just throw away. Both of those computers were only 3-4 years old. While anything remotely new would blow it away in performance, they are completely usable for daily use.
