I find that the market for 120mm aios is much less than the 240mm market, which results in less quality 120mm aios on the market. One fix to this would be the Asetek 650LS. It uses the gen 6 pump, doesn't require sata power, and fits well in the case. You can even customize the plate with a logo and rgb. I realize you probably have your hands full right now, but perhaps you could sell the Asetek 650LS through your site too, similar to how the Asetek 92mm aio is sold.
If I'm going to offer some sort of AIO, it has to
1. move the needle on cooling
2. show some data on the pump block like the Asus Ryuo or NZXT Z63/Z73
3. dump the SATA connector
don't have solution atm, so I don't want to do it.
