Why a customised Mac?

Some software packages - such as professional video or image applications - may recommend or require more memory and faster processors. Hard-core gamers may want to max out the memory or graphics capabilities.

In addition to helping you meet software requirements, maxing out your Mac can also help to make you more productive. For example, additional memory can let you do more things simultaneously - and have the computer work faster - when you get busy. People with large media collections will want the largest hard drives available.

What do these options actually mean?
