Ultimate Fish Room designs/locations

[bigmac]

Long story short, we are thinking of purchasing a new home. If this happens I want to create a masterpiece fish room.

What I know so far is that I'll upgrade my tank from 100 gallons to probably twice or triple that size. In addition it will be an inwall design.

Basically what I'm requesting opinions on is:
1. What is your idea of a perfect fish room? Please include any details/pictures/wish list equipment.

2. If this house is purchased, there is an opportunity to have the tank on the main floor utilizing the "formal dining room". Obviously I would have the builder enclose this space with moisture resistant drywall. There is a window for ventilation and I would ask the builder to reinforce the floor. My question is should I consider this as an option? My preference is to have the tank/fish room in the basement for floor strength, heat issues, etc. however there wouldn't be any plans of finishing the basement anytime soon. My family loves my tank and I would like to display it accordingly; but they hate the occasional smells from feeding time, skimmate, etc. I would also be able to utilize the basement floor drain if it was located in the basement; not to mention I wouldn't be constantly worried about water spillage on hardwood. Suggestions?
