PC-O9WX ATX Cube Case - Black

Lian-Li announces the PC -O9 chassis, the latest in its esteemed O-series open-air chassis. This new mid tower case features a distinctive dual-compartment design: one side uses all aluminum panels, the other is wreathed in beautiful tempered glass.

The PC-O9 is split into two sections for optimized cooling, organization, and style - it's like two different cases fused together as conjoined twins. Similar to the PC-O8, the primary compartment uses two large tempered glass panels spanning the sides of the case to showcase the motherboard, VGA cards, and overall flashiest components. The secondary compartment houses the PSU and drive rack in a windowless aluminum exposure. Both compartments are separated by a band running down the middle of the chassis, which contains the inputs and power button. No other case lets builders isolate different components into organized compartments to this degree.

Lian Li's Best Chassis for Water Cooling

The PC-O9 has the most flexible cooling layout in its series. It includes five 120mm fans - two exhaust fans behind the drive cage and three intake fans mounted between the compartments. The top panel in the glass compartment has three additional 120mm fan mounts; both top and bottom panels include removable mesh dust filters in this compartment. Water cooling enthusiasts can install up to two 120mmx360mm radiators, one replacing three included 120mm fans and another at the top panel in the glass compartment. To maximize space, builders can hide a radiator in the aluminum compartment, with rubber grommets for all-in-one tubes to pass inside the glass compartment. DIY enthusiasts will appreciate an included, removable mounting plate compatible with most pumps, with plenty of room in the back aluminum compartment for reservoirs and tubing.

Designed for Big, Beautiful Builds

The PC-O9 mounts VGA cards up to 420mm long, or 290mm with a thick radiator on the front fan mount, ATX PSUs up to 290mm, and CPU coolers up to 160mm tall. It offers eight expansion slots for high-end multi-GPU setups. The removable drive cage is tucked out-of-sight in the aluminum compartment and mounts as many as six 3.5" and two 2.5" drives for a total of eight, all mounted on rubber vibration dampeners. An included RGB lighting kit and controller is pre-installed, so builders can put together a clean, LED-lit professional-quality build right out of the box.

Lian-Li PC-O9WX Key Features

Premium cost and materials, premium feel

This thing is made entirely of premium materials. I was fed up with plasticky chassis and the tower look. My last case was a thermaltake level 10 gt snow edition but as I moved to closed loops for both graphics and cpu, it didn't have the mounting options for both rads. This case has bundles of space, really much more than you need, but I like it! The secondary space for cables and drives is a nice thought and does leave a clean and uncluttered look. I was a little worried about cooling as you have no rear extraction in the main compartment, just front intake, but that's taken into the drive compartment by the row of 3 fans included, and the rads offer enough extraction through the roof. It's the finish though, really slick, the metal is a really polished look and the glass is very thick slabs! As other reviewer mentioned, the lighting effect is brilliant, take some time to think of your placement as the adhesive is very strong and you won't get it off once it's set without damaging the light strips.
I gave it 9 because of the price, it is too much, but I do feel like I've bought something that's in a class of its own.

lovely case

first things first.this case is too last watercooled build was a corsair 900d and was very easy to work on,that thing was huge.
while not being a tiny case,i found it to be more difficult to work on,things like the drive bay cage and power supply have to go in after as they obscure the holes for the cabling.
not a big deal but worthy of mention.
everything is forgiven now is an absolutely gorgeous case.its quiet(must be the alloy and all that glass)the bundled rgb lighting kit works great and looks awesome.
did i mention its expensive? not when it looks this good,its worth the money.
