Leopard on my mac?

[rhys105]

When i buy leopard on the 26th D), i want to install it on my mac mini. i have 18gb of space left on my mac, how would i wipe tiger off and keep my files so that leopard can run more quickly?

use the archive and install option on the Leopard installer

use the archive and install option on the Leopard installer

that is correct, but he might not have enough space

It is better to do that (Archive and install) or to Erase and install Leopard?

I have quite a lot o things but everything is on my backup external hd. Plus i have XP in order to use AutoCAD on my macbook pro.

My idea was to clean install leopard (im a freak of perfection, thats why i use macs) then install every app i want to reinstall (i kept all installers too) and XP for autocad 2008.

Any thoughts?



EDIT:
Decision taken after reading a couple threads on this... Fresh install it is!!

will me apps of tiger run on leopard?
for instance: Cocktail (although i dont think leopard needs it), TechTool Pro 4, VLC, Flip4Mac WMV, Adium, Cabos, NeoOffice...

Oh and if it can help, i plan to do a fresh (clean) install...
