I sent in my application to join GMTower back in May of 2007.
It contained two videos and some text that is probably lost to the ages.
Back then I had a very old Dell desktop with an ATI Radeon 9700 graphics card (which needed to be under-clocked sometimes or the triangles wouldn’t stay in the right place) so the videos don’t look too good. 
Edit:
Oh hey you can still buy 9700’s for $25 hah!
