It is a shame how the panel covers it all, but if I were to remove it I would have absolutely no place to mount my HDDs and it would leave a hole all the way to the other side panel, which would uncover quite a few ugly cables. Mounting the pump/res would also be possible just on the psu cover, but that would require drilling and I'm not sure it would look that good. The case may have lots of watercooling support, but you need to sacrifice quite a bit to use it all...
