I think that would be a great addition to the forum. You could even do something like Evga forums do with a Mods rig section were we could upload some photo's of your rigs and put all are settings in.
Here is a example of mine there. Under your username you have your standard profile then they have this icon underneath your name.
The icon is click able which directs you to this page that has all my spec's and photos.
So essentially this is what it would look like on CF as a concept. With a clickable link to the above mod page with full computer spec's. Actually I'm not sure if you can see a mod rig without being a member so I'll paste what the link goes to. You can even add comments to users systems.
Click that view mods link system and it takes you to this page
