No need, they're side by side. Here you go. BTW, you can find images of any 360 motherboard online...all over the place. The images are pretty big (10MP camera), so if they take a while to load, it's because your connection sucks. Also you'll notice the extended GPU heatsink (GPU is on the left, the heatsink extends to the front of the CPU now) - they've been doing that since early 2007, and they also put them in all refurbished consoles.
Here's the two side-by-side - Xenon is on the left, Jasper is on the right. Both have had the DVD-ROM removed, since it would take up nearly half the picture.

Here is a closer image of the Xenon

Here is the Jasper - the green wire going across the NAND is in place because this console is JTAG hacked (plays homebrew, 500GB HDD, etc)

And here's a shot of them turned around, so you can see the Xenon (no HDMI) and Jasper (HDMI - under the regular A/V port) dissimilarities.
