I've been a long time reader of SPCR and have now built 3 systems based on what I've read here. So first, a very big thank you to all for amazing advice and discussion.
My latest build is a P150 with an 8800GTX, an Abit IP35 Pro, and an E6700, all bought new off NewEgg. A high powered gaming rig in other words.
Now, two issues. I have a horrible buzzing/whine (a lot like crickets on a hot summer day) when running intense 3D graphics. I mean the 'leave your ear ringing' type of sound. When I fire up the rthdribl demo the sound starts right away. If I click a menu the sound stops instantly. As soon as I release the menu it starts back up. If I change the mulitsample settings the sound tonals change. Specifically, 16x makes a really strange warbling/buzzing. When I take the side off and hunt the sound down, I'm almost positive it's coming from the power supply. I have a revision A4 with a little blue dot. Anyone have any ideas on how I can tame/eliminate the buzzing?
The second issue is that I definitely got the rubber o-rings, not the new fabric-reinforced elastic rings.
Did I get a bum case? I can't RMA it because of the notch for the GTX, but I don't want to have to spend a bunch of money on a new power supply.
Overall I really like the case, very easy to tuck all the wires into nooks and crannies out of the airflow. The only physical problem I had was notching the drive bay for the GTX. This is my first PCIe graphics card, and I didn't realize that the PCIe slot was not the topmost slot. So, I have an, erm, extended notch... No biggie.
[ Edit: I just realized that when I plugged in the two 4-pin molex to 6-pin adapter for the graphics card, I plugged them both into the same dedicated lead from the power supply. Should I feed each half of the 6-pin from different connectors to the power supply? Could shifting around the PCIe connectors to a different slot on the power supply make any difference? ]
