My old theme is kinda black grey as I used to have the 1080 windowed case, black speakers, logitech MX700 mouse and keyboard, except my monitor was completely greyish colour so the switch for me to the p180 still kept to the theme and looked pretty good. Sorry I dont have any pics to post of my setup. Might take a pic of my current setup atm to give u a better idea of what I mean.
Noise wise, I'm using all stock fans and a panaflo92mm set on low for the CPU. I've also moved one of the exhaust to the front so the case is a tiny bit noisier than if I had left the fan in the stock position. All case fans has been set to low. With this setup the case is near silent. All u hear are the wooshin sounds of the fans.
Vibration wise, close to nil but my fans are still new so it might change as they get older. Vibration from hard drives, the silicon dampeners does and damn good job! I can feel the HDD vibrates if I place my hands on the HDD but it doesnt travel into the chassis.
