As many here have seen, I built a cheap mini-itx box using hardware parts and one of the fanless 5000 boards. I find myself using it all the time these days. You guys know these are not the snappiest systems, but they do run DSL nicely.
I'm using my plexiglass computer most of the time. Just yesterday my Mother-in-Law (actually a very nice lady!) was over her and wanted to check her email. I asked her what she thought when she was done. She said, "That was strange, I am use to being able to hear the computer turning on .... It was almost eerie."
I could understand what she means, the first couple of times I ran it with the other computers turned off it felt a little unnatural to me too. Yet, something happens after a while. The switch gradually makes you end up loathing the noisy sounds of a standard desktop. These days I only boot up the big computer when I need to do some development work and the whole time I have my big noisy machine going I want to hurry up and turn it off. Thank goodness I am not a hardcore gamer.
