Internal or External overflow... Help choose.

I'm looking into picking up a 6ft planet aquarium tank and am trying to decide between internal and external overflows. I really like their ghost style overflow and how open it keeps the tank but I think I could get away with a wider tank if I go with their internal overflow.

I'd probably have to go with a 24" with the external overflow but could get away with a 27", possibly even 30", since the tank can be closer to the wall with the internal.

I'm thinking that the wider tank makes up for the space taken up by the overflow but am open to hear the pros and cons of either way.

Consider keeping some gap in the back for tank for access, maintenance, cleaning up water spills etc. I have and internal overflow and no longer like the fact there's a hole in the bottom of my tank and it takes up lots of space. Good luck either way!

I'm going to go with external. Thanks for all the responses.
