Personally I would leave it to the processionals to direct import from China, if you think you were buying a brand name there's a high probably of getting a counterfeit.
Just don't let too much time pass you only have 40 days to make a paypal charge-back request, some sellers have been known to string people along with promises until that 40 days passes then they go black.
Obviously yes. You can't buy a computer like this for $30, anywhere. You just lost $30. Consider that a stupid tax and move on, because wow, if you think this is legit, life's going to throw you a lot of curveballs. Time to get a bit more critically aware of your surroundings here.
You didn't state your payment method, but if you paid via Paypal then open a dispute with them. Otherwise open the dispute directly with eBay.
why would you ever buy a computer thru ebay?
No.
