Since I like building the mods that I use, I went to OshPark's Shared Projects page and found a couple XenoGC clones available. I decided to go with one that was simply called 'Yet Another XenoGC Clone' by jskyboo. It's a XenoGC Clone with ISP header.

I chose this version because I liked how it attached to the drive PCB better than the other options. However, on two of the three drives that I modified, I had to move or rotate a surface mount capacitor as they were in the way of the bottom right side of the PCB. In the attached picture, you can see a wire going from one capacitor to another just under the right side of the mod PCB. That capacitor was factory installed with a solder blob to the other capacitor and connected to a via. Odd, but easy to move.
I know the XenoGC has been around forever but this is the only mod I saw that had all the solder points together like this. The only downside was that the PCB is bigger than other XenoGC mods. I couldn't find any pictures so I figured I'd share this neat design with everyone.
