Some minor corrections - XSPC do indeed make G1/4 adapters for the top fill port. There will be a version with multiple G 1/4 ports in future. The Dual DDC top is designed to be mounted using the pump base, and the D5 nylon clamp has been verified to not leak despite only having 4 screws. Flow numbers on the D5 top are very promising.
