Problem getting my emails back from Outlook and Mail

When I sold my Mac Pro couple of months ago I totally forgot to export my mails from Outlook and Mail. I still have the HDD on which the emails are on, but when I tried to access them from a different computer it wouldn't let me recover them. (Tried to connect it via SATA to a hackintosh computer)

I know if I just plug my HDD into another Mac Pro I could boot up from this drive easily and access all my emails but the problem is I don't have a Mac Pro anymore.

10.6 does not(?) support SB-E so inserting my old HDD into a new MP (when it comes out and when I buy it) would not be an option.

What can I do at this point to access all those emails?

 

Thanks! I guess I would be in the similar situation as when I tried accessing my outlook profile via a Hackintosh. For some unknown reason it did not let me use "the old" profile.
