Most people prefer to fit a sump directly under their tank in a custom or store bought stand. Others run their plumbing back and forth through a wall and hide their sump in a room behind the tank. You can take that idea a step further and install your tank into a wall with a fish room behind but that's a big commitment. If you have two stories you can put your sump on the lower floor if you buy a powerful enough return pump. I've also seen setups where a sump is hidden under a stairwell beside a tank or creatively hidden in some custom or modified furniture like a cabinet adjacent to the tank. Then there's mine which just sits slightly to the side but basically in front of my tank... I really wouldn't recommend that though.
