I've read a lot of posts requesting Dell Optiplex series stencils for Microsoft Visio. My company sells Point of Sale systems and we use Optiplex exclusively and I have made a couple stencils over the last year or so. The GX520/620 Tower and SFF machines and the GX50-GX280's are covered in it. However please note that the GX50-GX280 Towers and SFF machines look almost exactly a like so I use the same image for both (hand crafted myself). So enjoy. Here ya go!

Hosted on my own space so be kind and share. You may NOT charge for this, I will check the net to make sure that no one steals these, this means YOU NETZOOM.
