In agreement that the Gigabyte response to the oscillation is ridiculous.
But since the warranty is now voided and you have the noise problem I might
try throwing in some fabricated rubber washers between the PS and the case
to just try to limit any kind of vibration and see if it could help to stop
the noise. If it doesn't then it's completely a problem from within the PS
case and for that I would be contacting Gigabyte for either a replacement or
refund of your money. Adding a few inches of wire onto the cpu connector
would have nothing to do with the oscillation.

It sounds to me like the PR person responding just didn't know about the
BTX spec for bottom mounted PSUs and was trying to justify why anyone
would put a PSU down there. You should have just returned it before
voiding the warranty since the cables were too short, IMO. I'm sure there
are PSUs for sale where the cable lengths are listed.

I was a loyal Gigabyte fan for several builds (with a single Super Micro
transgression -- The single best board I've ever owned), so I didn't
even think twice when I was hunting for a new PC.

I don't even recall the model number anymore, but it was high end and
too new to have any real reviews (okay, that was my fault), it was just
a case of one thing after another didn't work, had quirks, etc.

The board was barely stable in it's default configuration, some of the
components just didn't seem to like each other, stuff like using both
on-board RAID and higher bandwidth USB 2 devices would bluescreen, their
solution would be to stop using one or the other to make the problem go
away, then the case would get closed.

I had RAM compatibility problems, their response was to look at their
list of compatible RAM. The fact that my RAM was on the list, and was
proven-good in another system didn't seem to matter.

Unfortunately for me, a couple of my friends bought identical systems
knowing that I'd have done all the research and only bought quality
gear, we all had similar issues, so it made me look like an idiot.

Eventually they offered to swap my board (although not my friends'
boards) for another one, I suggested a different replacement since the
one they suggested was missing Firewire headers (just had ports on the
back, so it met their checklist of compatible features) or something
specific I wanted, so I suggested a cheaper replacement option, they
agreed, shipped their initial offering anyway and refused to discuss the
matter since I had received a more expensive board.

This being my first, last and only experience with a motherboard
manufacturer's technical support, I was rather disillusioned.

I eBay'd the replacement, switched to ASUS and haven't looked back. Not
that the ASUS has been 100% painless, but it does what I need.

Honestly I realize it's probably a one-off anecdotal case, and everyone
makes a lemon here and there and horrible support isn't really
unexpected these days either, and given that I so rarely use tech
support, shifty support isn't a deal breaker -- The lesson is to buy
from a vendor with a better return policy.

This is a pretty major benefit, my P180 is massively heavy, but it's
very stable due to having such a low center of gravity with the PSU and
drives mounted as low as possible.

The concept of separate head-zones is handy too, as is the better
airflow at and around the CPU.

I suspect it wasn't an intentional design decision, as much as just the
way things ended up when desktop cases got turned on their sides and we
got towers.

Are you sure it's the PSU? If so there's only one thing it
could be, an imbalance fan. Swapping the fan should resolve
the problem, though a fan that bad would have been a
reasonable reason to return the unit for replacement or
refund.

Ok, but sometimes vibrations make something else resonate.
Pressing down isn't necessarily evidence, BUT if you were to
stick a plastic drinking straw into the fan intake near the
hub to stop the fan, with it no longer spinning and no other
pressure applied to anything in the case the noise should
stop.

A significantly imbalanced fan will wear out faster. It
could be worth the expense of a new fan, or merely time if
you already have a suitable one, to replace the fan now
rather than possibly having to do so later... especially
when the modification to the wiring has voided the warranty
so if it fails in only a year you have no recourse but to
buy a new PSU.
