Ok you may have misinterpreted the mods they are totally different. One mods the motherboard and one mods the CC. The differences are you cannot return the CC to normal easily if you do the video mod to the CC's hardware (meaning you cant put the original motherboard back in without extra VRAM) and the hardware of the CC screen is now at higher voltage which taxes those parts harder than normal. If you do the motherboard mod then you can leave unit intact, and replace mobo's however you want and it doesnt hurt the CC hardware more than normal (no extra voltage through alost twenty year old parts). The outcome is the same but one is harder on the CC unit and one is not. I have done both ten years ago but they were only ten years old then.

Good Luck on your mod decision either way.
