Street Price

Over the years Lian Li has produced their fair share of mini-ITX cases in their well known all-aluminum style. The last three models we reviewed all offered ATX power supply support and more notably, multiple hard drive bays. The latter is great for servers but rather wasteful otherwise. For the many users who only have one or two drives, the drive slots needlessly take up a substantial amount of space inside the chassis. The extra room could have been better utilized or shed entirely to make the cases sleeker.

The Lian Li PC-Q10.

Their latest mini-ITX offering, the PC-Q10, does exactly that, keeping potential storage to a minimum. With a total volume of under 19 Liters and a gorgeous side panel window, it’s easily the slimmest and best looking Lian Li enclosure ever. While its pedigree is well documented, the optical drive slot at the top is reminiscent of the NCASE M1, the similarly elegant and compact all-aluminum case famously crowdfunded, and built on contract by Lian-Li. The PC-Q10 is not quite that small as it can fit a full-sized ATX power supply as well as a 120 mm exhaust fan. Cooling seems to be well addressed with a fully ventilated top and bottom compensating for the solid front and sides panels.

Box and case.


The PC-Q10 ships in a rather plain cardboard box with protective sheets covering both sides of the acrylic window to ensure it arrives scratch free. The accessories are contained in a small white box tied to the interior of the chassis. Inside are all the necessary screws, rubber grommets for mounting drives to bottom of the case, a PC speaker, three zip-ties, and a couple of cable routing hooks. A brief assembly guide and case badge are also provided.

The Lian Li PC-Q10 weighs 2.3 kg or 5.1 lb and is composed of an aluminum exterior with an acrylic side window and a steel interior. It measures 20.7 x 27.7 x 33.5 cm or 8.1 x 10.9 x 13.2 inches (W x H x D) for a total volume of just 19.2 Liters.

The PC-Q10 has a striking aluminum front bezel with a smooth surface so you get the stylish look of a brush finish but not the rough feel. The control panel is located near the bottom and features USB 3.0 and audio ports. The glitzy jewel of a power button is also composed of aluminum with a tiny hole in the center for the case’s almost imperceptible blue power and red drive activity LEDs.

The front and top are actually part of a single L-shaped piece with a bevelled corner. Towards the front is the slot for an slim optical drive while the rest of the panel is covered in ventilation. Mounting holes are provided for two 120 mm fans though the one closest to the front is not usable as it would interfere with the power supply mounting frame.

A 120 mm exhaust fan is pre-installed at the back and covered with an old school wire fan grill rather than the more common honeycomb vent. The AC power cord attaches on the side next to the I/O panel.

The underside is wide open, as ventilation slits abound. Two 120 mm fans can be installed here or alternatively you can bayonet mount three/two 2.5/3.5 inch drives.

The acrylic window is a substantial 3 mm thick and attached using four thin plastic black thumbscrews. The panel is well secured and should do a decent job of keeping noise in.


There is not much to say about the interior construction as it’s essentially a hollow cavity aside from the fan, motherboard tray, and drive and power supply mounts attached around the edges. The motherboard tray is thin but does stretch from top to bottom, lending the structure some stability.

The interior.

The box protecting the front port connectors is positioned such that it lines up directly with the graphics card, limiting the maximum length.

Cooling is provided by just a single 120 mm fan at the back, a seven blade 3-pin 1200 RPM model.

The power supply is mounted to a bracket with the exhaust side facing upward. Along the front is a vertical drive bracket that can accept either a slim slot loading optical drive or a 3.5 inch hard drive.

The anemic motherboard tray is more like a frame outline and there are no dedicated points for tying down cables. The AC power extension cable runs behind the motherboard.

The border frame underneath the side window and the right side panel are held on using a tool-less standoff/slot system. The top/front panel piece is secured the same way but with screws at the rear and bottom of the case providing additional support. Panel thickness is about 1.3 mm.

There seems to be several errors in Lian Li’s specifications. The max CPU cooler height is closer to 160 mm than 140 mm, a 240 mm radiator at the top would block the power supply, and the fan mounting holes at the top are for 120 mm fans, not 140 mm.


Putting together a system inside the PC-Q10 is easier than most mini-ITX enclosures due to the removable panels. The sides, top and front all come off, so there’s plenty of room to work. Connecting cables to the motherboard may be difficult if you have a large CPU heatsink installed depending on where the connectors are located but that’s true of almost all cases. The assembly process is fairly straightforward otherwise.

Depending on your preference, the power supply can be mounted directly to the bracket from within the case or you can install the bracket outside the chassis and lower the PSU in. The orientation is such that the intake fan faces the motherboard.

3.5 inch drives can be mounted to the bottom of the case using rubber grommets but with a dual slot video card in the way, only 2.5 inch drives fit. The only space for our SSHD is the vertical position at the front of the case. The bottom of the drive is in completely contact with the bracket. With no form of damping or isolation, vibration will likely be an issue.

Our test system fully installed. Normally we would use an Asus GTX 980 Strix or Zotac GTX 970 Extreme Core for the video card but both are too long for the PC-Q10. Our third option is an Asus HD 7870 DirectCU II which measures approximately 27.3 cm across.

Lian Li lists the maximum CPU cooler height as 14.0 mm but our 16.1 cm tall Scythe Kotetsu fits almost perfectly. The heatsink presses on the side window, making it bulge outward ever so slightly.

Bending the front connector cables as much as possible leaves about 9 mm of clearance between it and the edge of the video card, making the maximum GPU length approximately 28.2 cm or just over 11 inches.


21~29 mm of space is provided behind the motherboard tray. It’s a little tight as cabling causes the right side panel to bulge out slightly near the center.

Testing Procedures

The system is placed in two states: idle, and load using Prime95 (2 out of 4 possible threads, large FFTs setting) and FurMark, an OpenGL benchmarking and stability testing utility. This puts more demand on the CPU and GPU than any real life application or game. Throughout testing, system temperatures, noise levels, and power consumption are recorded. During the load test, the system and GPU fans speeds are adjusted to various levels in an attempt to find an optimal balance between cooling and noise while maintaining a GPU temperature of 85°C (at an ambient temperature of 22°C).

Baseline Noise

For our baseline noise tests, the system is left idle, the CPU and GPU fans are set to their minimum speeds. The system fan(s) are connected to controllable fan header(s) and are set to a variety of speeds using SpeedFan. This gives us a good idea of what the stock fan(s) sound like at different speeds with minimal interference from other sources.

Measuring mic positioned 1m at diagonal angle.
Ambient noise level: 10~11 dBA@1m.

When the system fan is disabled and other fans set to minimum speed, our test system measures a very quiet 16~17 dBA@1m. The case fan can bring that figure up to a moderately loud 26 dBA@1m at full speed and can hit any SPL in-between depending on the fan speed. A single moderate speed single 120 mm fan seems insufficient for a small cramped case but the healthy amount of available ventilation should help compensate.

The noise quality is poor. The stock fan is subpar, producing a prominent clicking sound at 50~100% speed that for, some reason, our mic fails to pick up. A low pitched hum starts at 50% speed as well but this dissipates as the fan ramps up. Being hard mounted to the front of the case, our 7200 RPM SSHD’s vibrations can be felt and heard easily as evidenced by the tonal peak at 120 Hz.

If mechanical storage is a must, a low vibration 5400 RPM drive should be utilized. The drive placements on the bottom of the case are better but a 3.5″ drive can’t be used in combination with a dual slot graphics card. Swapping out a fan is easy enough but there’s no simple solution to limit drive vibrations. Placing a block of stiff foam between the power supply and drive helps but not enough to change how the machine sounds.

A few minutes into stress testing, it was soon realized that the stock fan barely had to do any work to generate quiet results. Under our standard testing parameters (two threads of Prime95 combined with FurMark), the CPU fan running at minimum PWM speed was sufficient to keep the processor comfortable while the GPU fans only required a 250 RPM speed bump to maintain a 85°C GPU temperature. The resulting 17~18 dBA@1m SPL was lower than the 19 dBA@1m produced by the stock fan running at 60% speed during our baseline tests so it can’t get much quieter.

Striving for an 80°C GPU temperature only cost an extra 1~2 dB. Adding a third thread of Prime95 (four threads interferes with GPU usage) made the CPU and motherboard heat up a few degrees more but the noise level was unchanged except for a slight increase when shooting for a GPU temperature of 85°C (the power supply fan probably sped up slightly to deal due to the warmer conditions).

Compared to our baseline tests, the acoustic quality of the system actually improved under load. The SPL is only slightly higher and the GPU fans emit more high frequency noise, helping balancing out the low-pitched hum of the stock fan.

A properly cooled system with our usual reference GTX 980 draws around 280~290W. Our HD 7870-equipped PC-Q10 enters this power consumption range when a third thread of Prime95 is added as a stressor, coming close to compensating for the difference in GPUs. With this equalizer in place, the noise difference between the PC-Q10 and competing mini-ITX cases we’ve recently examined is substantial. The black variant of the BitFenix Prodigy comes closest but trails by 2~3 dB. It’s an impressive feat considering the PC-Q10 is much smaller and has just the lone case fan.


These recordings were made with a high resolution, lab quality, digital recording
system inside SPCR’s own 11 dBA ambient anechoic chamber, then converted to
LAME 128kbps encoded MP3s. We’ve listened long and hard to ensure there is no
audible degradation from the original WAV files to these MP3s. They represent
a quick snapshot of what we heard during the review.

Each recording starts with ambient noise, then 5~10 second segments of product
at various states. For the most realistic results,
set the volume so that the starting ambient level is just barely audible, then
don’t change the volume setting again while comparing all the sound files.


The PC-Q10’s heavily ventilated chassis allows air to pass through the case with ease. As a result, our test system was surprisingly easy to cool sufficiently — the single included case fan only needed to run at 40% speed and the CPU fan never had to exceed its minimum speed. Lowering our GPU temperature standard and stressing the CPU more than usual barely made a dent in the overall results. The noise level was phenomenal, staying below 20 dBA@1m throughout all our torture tests.

From a objective standpoint, the PC-Q10 is a very quiet case purely due to its impressive performance but the noise quality of its lone fan leaves a lot to be desired; it is a clicky annoyance begging to be replaced. The front drive mount needs some kind of damping as the hard mounting is unforgiving about vibration. It’s the only place to install a 3.5 inch drive unless you go forgo a dual slot graphics card.

The placement of the front control panel is unfortunate as it limits GPU length just enough to make some popular high-end cards unusable. With space inside a mini-ITX case being so limited, I wonder why a SFX power option was not offered. An ATX power supply does cover up more cables, but that really should be the motherboard tray’s job. The tray is anemic and doesn’t extend toward the front of the case so it doesn’t hide cabling very well. It should also be noted that there are some mistakes in documentation, the most notable being the maximum CPU cooler height being off by 20 mm, and the Lian Li site touts 240 mm radiator compatibility at the top as a feature despite the fact it would interfere with the power supply.

The Lian Li PC-Q10 is a compact case that perform well while looking elegant. Its striking brush aluminum finish and sizable side window makes it stand out among its shabbier-looking competitors. That being said, the PC-Q10 gives off a vibe that suggests it was designed by engineers focusing on the big picture, rather than PC hobbyists putting extra effort and consideration into the little things. If you had to choose one or the other, it’s hard to argue Lian Li didn’t make the correct decisions. The PC-Q10’s tremendous airflow and attractive aesthetics more than compensates for its deficiencies.

Our thanks to Lian Li
