Here are front and side pics of my G4 (two seperate posts, I think you can only do one at a time). It's 867 Mhz, 896Mb RAM, 60 GB HD, and all the other standards for this model.
Sorry about the flash, I couldn't turn it off on my friends digital camera. If you want more shots of specific views or components of the comp, just let me know here and I'll take em.
