Is it possible to find QNAP TS-409U replacement parts

Is it possible to find reasonable cost replacement parts for a 1U QNAP NAS device? A QNAP TS-409U, no device page for any QNAP stuff yet.

I could use a new power supply for this model I listed above and have not been able to find anything from regular searches. I will be calling around during normal hours tomorrow, but thought it could not hurt to ask and see if anyone had a online resource i am not aware of for a device like this. ( i would hope a power supply would not be terribly expensive, this is my fear and another reason i am asking) these types of devices are fairly expensive to purchase and of course replace if not repair is not possible.
