libreoffice is great for drawing out networks

  1. is free
  2. and has good icons

Best used with the libreoffice-draw package and the VRT Network Equipment Gallery extension for a small set of high quality Network icons images optimized for libre.

There were no sheetmetal cutout frames or GPU icons, unfortunately.
