I was mistaken. I have a 250mL res. It is possible to mount it, but there is no way to get a pump directly underneath it. Just from a practical standpoint, a bay res seems the easiest. Or a small 100mL or 150mL res and use one of the HPTX standoff holes to mount the clamp. Or, depending on your pump, a res affixed directly to the pump. The braces also offer a variety of modding options. Could mount a few rads with some modding. I almost want to spend a couple days just trying to wrap my head around it.
