Dia server shapes

I have been using Dia to document network architecture recently, and found that there were no satisfactory shapes for rack-mount servers so decided to create some and in the spirit of this kind of thing make them freely available:

They are only 2D and contain no internationalisation, but the meet my needs and if you think you could use them then please do so. Comments and feedback welcome.

As a general query, how many people here use Dia, and what for? If you use something else for network diagrams, what do you use?
