The PC-B12 installation kit includes an exhaust duct with a noise dampening sheet, a USB 3.0-to-2.0 internal header adapter cable, a PC speaker, and several bags of screws.

Lian Li created the PC-B12’s front intake duct by moving its fans back and blocking the front of the case. This forced the company to move the hard drive cage closer to the motherboard tray, which in turn leaves no room for anything larger than a standard ATX motherboard. Unfortunately, many of today’s high-end motherboards are oversized.
Although our test motherboard is 7/8” wider than the ATX specification, we were still able to make it fit by removing the motherboard tray bracket. It was an extremely tight fit though, forcing us to bend the board’s front-panel connector pins downward in order to connect the power and reset switches. We accidently reversed the power and reset switch headers, but used the buttons in reverse rather than fight with the hard drive cage yet again. While this particular problem only affects slightly-oversized motherboards, boards any larger that Asus' P9X79 WS will not fit in the PC-B12 at all.

The PC-B12’s SSD mount uses shoulder screws with noise-dampening grommets, much like the hard drive trays in many high-end cases. Unlike 3.5” drives, the case only supports a single 2.5” SSD. If you plan on rocking more than one solid-state drive, 2.5”-to-3.5” adapter brackets, packaged with some drives and available from multiple vendors, are always an option.

Even without much room to stash cables, our modular power supply allows for a relatively clean installation. Really fussy builders could finish this off using cable ties in less than an hour.

While the PC-B12’s rear exhaust duct is fully-adjustable up to 45 degrees, time limits only allow two tests per case. Rather than make an exception for Lian Li, we tested the PC-B12’s rear duct at the two extremes: completely closed and with the duct removed.

Thanks for that; I was wondering when it would arrive.
He is running dual AMD 5850's with axial fans and a Corsair H50 water cooler cooling an AMD 8150, it's very quiet even at full fan.
In my P280 I have a OC Intel i7-3770k with an Antec 920 water cooler and 2 scythe 2k rpm fans, with the scythe at full power and the 920 on aggressive thermal settings it keeps he 4.7ghz oc under 50 deg c under almost all loads while not being excessively loud.
It would be interesting to repeat the tests with an axially-cooled graphics card. After all, that style of cooler would be the choice of someone building for low noise. Of particular interest would be the resulting temperature differences, especially of the Silverstone.
Toms, thanks for doing this series it was really nice to see the time and in depth detail put into this. I will be bookmarking these for reference on my future builds.
Half finished building with it last night. Once you get th R4, you can tell that a lot of thought went into building this case. I'm still a novice when it comes to cable management, but FD makes it real easy. For $80, IMO, you're getting a steal.
Yea this competition combined with the killer R4 price is a no brainer for me. I was going to get the corsair 550d but not now.
I'm disappointed that the Corsair did so poorly with noise reduction, I thought from previous tests elsewhere that it did fine with that but had some cooling issues that could be resolved by removing the HDD cages and loading up all the fan postions. Unfortunately it seems that it would be louder still in that configuration.
Nice review, guys. I appreciate it...

P183 ould have been interesting alternative. It should be more silent than p280? but harder to build because of dual chamber solution. Still it would be nice to see it compared to P280, if there are any real differences. If I am building silent gaming machine the case can be even a little bit more expensive if it can achieve good results. You can get gaming casis really cheaply, but they are definitely not silent...
What are you referring to?
(just curious...)
Maybe ask for your money back?
Sorry, but it bugs me when people whine so much about such minutiae. You're getting a lot of informative content for free. How do you think they feel after doing all this testing and writing to see snarky comments like these?
