I'd do the following:
- fix my apartment
- buy a good computer (maybe two
)
- buy apartments and houses in this town (very cheap because of local currency)
- save the rest in a bank to pay for stuff via debit card
- start paying for what I have on my PCs
- randomly donate 5000 USD to the freeware projects/programs I like
But since I don't have 1,000,000 USD, I won't do any of that (in bold).
