depending on your windows use you can do vmware fusion to install windows 7 and the seagate drive will run windows and lion at the same time.
you could also install bootcamp on the internal. not ideal but a half way decent workaround for some users.
completely and totally off the subject i built my first pc.
uses an intel i 2500k pretty nice but not quite what I want.
it would be exactly what I want if it could run lion legally oh well
I did purchase Fusion, and honestly for the amount of time I might need to boot native, another install to the internal drive is probably fine... I'm just already spoiled by the speed of the SSD though
