There are a few issues. First, I do not believe there is room for the end caps of the reservoirs of the all-in-one units you are proposing in the case.



Next, there is no major advantage of the ASUS Impact board, unless you're really set on using something like the Intel 750 SSD drive. The Z170I Pro Gamer board has an M.2 slot that the Impact board doesn't, too.

The G-Skill RAM doesn't really buy you anything, either. If you want additional storage, like an SSHD, I'd suggest buying and installing it yourself.

To get both the CPU and GPU water cooled, I'd suggest using a set-up like this:
