Some notes about my experience using the Raspberry Pi model B…and you get it running Linux Debian on it!

The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.

We don’t think that the Raspberry Pi is a fix to all of the world’s computing issues; we do believe that we can be a catalyst. We want to see cheap, accessible, programmable computers everywhere; we actively encourage other companies to clone what we’re doing. We want to break the paradigm where without spending hundreds of pounds on a PC, families can’t use the internet. We want owning a truly personal computer to be normal for children. We think that 2012 is going to be a very exciting year. [About Raspberry PI]

After some years of use, you’ll notice the increase noise coming from the cooling system. Any ventilator on the market, even the more expensive, or the more silent will wear off and start making noise. Replacing the ventilator is done in less than 2 minutes if you follow this little how to.

Choosing the right ventilator

• Don’t pay too much, better choose a cheap model and replace it every year or two
• Below 19 dB, it is difficult to hear a ventilator running, don’t go over 22dB noise
• You need a 80mm x 80mm x 25mm it is a standard size, you cant go wrong in a shop (other common size are 92mm and 120mm)
• Check that the connector is a 3 pin Molex.
• It need to run on 12volts, the lower the voltage, the lower the noise, but too low and the NAS may overheat since the air flow is also reduced.

I paid this Xilence case fan 8 euros, sold as being silent 15dB, 1500 rpm, 18.67 CFM, not running below 7V.

You can safely choose any brand:  Papst, Be quiet!, Revoltec, Zalman, Noctua, Noiseblocker, all of these are good if they meet the above requirement, unfortunately the were not available in my favorite shop (www.digitec.ch)
