Migration to Leopard?

So do I buy a more powerful mini, which comes with Leopard and Ilife 08 or do I just drop the coin on the software alone?

anyway: list of apps I need to perform the clean install:

adobe cs2 (nah... don't really use this much)
adobe acrobat pro
dreamweaver
fireworks
flash
parallels
windows xp sp2
visual studio 2005 (or beta 2008?)
fireworks
toast (does 8 work?)

files:
docs
music
photos
