Power brick too loud for my taste?

That's exactly what I did, or had to do. But i'd rather wait a few days. I just hope the replacement unit will really be silent, or at least not that noisy.

Honestly since iv'e never had to send mine out unsure if they will send a new brick or entire new machine....i'd assume just a brick to save themselves money and time?

Not had my replacement PSU yet, one week after it shipped.

The email said it can take up to 28 days, though...

You must've just been unlucky, I've had to use the support on 3 seperate occasions and found that I had replacements with me no later than 10 days from despatch to delivery.

Hope it is just a bad power supply unit. Had mine over a year, can't ever hear it. That and the system are so quiet.
