Hi Eric,
Sorry that we don't have the Titan One XL 3.0 in America.
But we have the distro plate on Newegg, as the following link.
You can install a 360 radiator with fans on the top and it to the distro plate by the fittings and tubes, such as BPTA-DOTFH1622-GS and BP-CLT16-R11X41.
If you have any questions, feel free to contact us.
