Can I swap out my 380W PSU for a 600W OCZ?

[Rollingstone]

A case-related question: I have an Antec Sonata 380W ATX12V True power PSU. Specs located here: http://www.ascully.com/modules.php?name=Reviews&rop=showcontent&id=230

Can I simply remove its PSU, and put in, for ex., OCZ's 600W PSU. Its specs are located here:

Or must I find an ATX-only PSU?

Please let me know soon...and sorry for the green question.

Also, IYO, would I get a better selling-price in Ebay by selling it w/the PSU?

That PSU will fit in there no problem.

Which PSU? The stock one or the new one? If it's the old one it may help, or it may be of no interest, it depends on who is looking at it. If it's the new one it would definitely make a difference.
