A tower looks cool, but it's a waste
Bars have chilled towers that keep the beer cool, often with a glycol system. Homebrew towers have a thin piece of foam, that'll work for the same night, but if you leave it overnight the beer will taste off the next day and you'll want to clear the tower. You can rig a fan of some sort to circulate the cold air up into the tower and avoid that, but learn from my mistake: just use the shanks.
With the money you save you can buy forward sealing faucets like perlick. Those are a much better use for your money. They're all stainless, don't stick like traditional faucets, and don't let air get into the line so the beer in the line doesn't really stale that much.
