Be careful that the bottom pane of glass is not tempered (can't be drilled). Otherwise, you're ok.

For dimensions, a 4' tank with a volume of only 50-75 gal is going to be very narrow (front to back) and will make aquascaping and flow VERY difficult.

I don't know if you're trying to fill 4' of wall space or trying to keep to a specific maximum number of gallons, but a 4' tank will 'normal' dimensions will be at least 90 gallons. I would concur with what others are saying about the tank size, too. Go for the largest tank you can practically afford -it will save you from the constant upgrade syndrome we all go through (I'm starting the upgrade process from a 40 gal to around 110 gal now).
