[plug] OT (?) low heat & low noise linux box for firewall?

[Daniel]

Hi, just wondering if anyone has any suggestions for a quiet machine to
use as a linux firewall - and one that won't mind my room which has all
the benefits of being cold in winter and hot in summer.

Has anyone tried the new Via (~Cyrix) chips?

And the low-end Intel chips - I wonder if there are any good 'low-noise'
cooling solutions?

Any ideas would be appreciated as I should pension off my old box before
it dies.

Thanks,
Daniel.
