tailor your build around your goals not looks.
for example, if you are building a car for road racing and want quick response, and dont care too much about peak numbers, getting a top mount manifold would be a waste of money. The same can be said if youre building a drag car that will be seeing high horsepower, torque, and a high redline. in this case an equal length manifold would be better than choosing a log style, or cast iron style manifold.
Do a little research and find out what you are primarily going to be using your car for, and build your car to suit those goals. Create a budget and go from there.
Half size radiators are not always needed, you can get away with full core rads depending on your manifold and turbo choice.
