Can turn the res upside down. I use a Bitspower tube res so I use the 3 port at the top. The tube inside the res ensures the fluid doesn't get agitated and I fill it there and use the air outlet.

a crossflow simply has an port at each end typically at opposing corners. the rad you reference is NOT a crossflow. if you look at the image both ports are at one end

I wouldn't recommend it, the top connection is really for filling the loop up, but it is possible use it if you have another fill point, the only issue with it is it then becomes a mare to bleed as you always get air collecting at the top of the res you can't get rid of which then ends up in your rad when you switch the pump off.
Hmm.. My plan was to use a res with the input in the top. The res will have two top inputs, so one for filling. Any recommendations on how to avoid air moving back up to the rad? Would I just had to fill the res completely? Is that too much hassle?
I've come up with what Bitspower calls an 'Aqua-pipe'. Will that work with any g1/4 port on my res? It looks nice and shiny, so if yes it's definitely on my shopping list.
