Further to what Craig was saying:

One of the ideas i continually fight is the idea that Linux is cheap.
Just because Linux doesn't require the same hardware requirements as
other OS's doesn't mean you should skint(?) and choose the cheapest.

As Linux professionals we should try to provide Linux with an ideal
environment as is possible. We don't just sell Linux as cheaper, we sell
it as being better, more reliable and more suited to the clients needs.
Therefore we don't pick the cheapest parts.

While i hate to say it some of the M$ servers i see are more reliable
than the Linux servers clients get me in to fix. This is because people
have sold Linux to them as being more reliable on buggy(cheap)
hardware.  Linux *can* work around a lot of buggy hardware but why
should it, when the software is at least cheaper if not free. Don't
undersell Linux!

We are not in the world of the Pentium 166 anymore. I loved the under
200Mhz Pentiums, we could put them in an oven and they would still
perform. We live in Gigabit LANs and hyperthreading CPUs and Linux does
need more than 16MB RAM to get performance.

So please to guys/gals selling Linux; Help Linux. Don't do it cheap do
it right!
