Prices for Apple computers are generally on the higher end, but their latest offering could potentially break the bank. Unveiled Tuesday, the new Mac Pro starts at $6,000. Depending on the combination of parts, the price can climb over $52,000 for a fully loaded model. Dubbed the "cheese grater" due to its design, a display is sold separately. Want the monitor to match? That will set you back an additional $5,000. But the one accessory that has tech writers scratching their heads is the attachable wheels that allow the tower to be moved around with ease. While optional, those run $400. How did you choose your current computer? Off the shelf or did you build it yourself?
