5 out of 5 eggsGreat Little Case - Plan Ahead

Pros: Very nice fit and finish. Classic understated look was perfect for my needs. Build was pretty straightforward as long as you plan ahead. Obviously space is very tight so plan every connection in advance. My build order - mount the DVD drive, mount the SSD, mount the mobo to the tray (removed from the case), attach the from panel power/LED wires, re-install the mobo tray, taking care to ensure the reaer IO shield is fitted correctly(had to remove the first time due to one of the tabs on the shield was inside the HDMI connector). Attach SATA and front panel USB connections, Last step was to connect the power supply connectors then slide the PS into place. A modular power supply is a huge help. An SFX power supply gives you a little more room. I went with an ATX supply I already had from a previous build. It's tight, but it works. I personally like the snap on side panels, made it really easy to take them off and put them back on, and they seem adequately secure.

Cons: Not really cons - just some personal nitpicks to be aware of.
The power LED is quite bright. Can light up a small room at night.
The SSD mounts flush to the bottom mounting bracket making it difficult or impossible to use a right angle power or data cable.
The IO shield is pretty flimsy (aren't they all) and I wish it came in black.

Other Thoughts: Lian Li thoughtfully included the tiny M2 size screws used for the slim DVD drive. Saved me a trip to the hardware store!

Very happy with the case. Would recommend and buy again.

4 out of 5 eggs

Pros: -well-made, solid aluminum case
-small and compact
-option to install slim optical drive or additional 2.5in drive
-removable motherboard tray for easy motherboard installation or upgrade
-drives install with rubber anti-vibration washers

Cons: The feet on the bottom of this case are basically dimples the case's aluminum base. Depending on the surface the case is on, the case may slide around when you plug in peripherals such as usb drives or headphones. Rubber feet, like some other Lian-Li cases have would be better.

You will want to inspect the feet for burrs and remove any you find with fine sandpaper, as my case had burrs on the feet.

Other Thoughts: If you don't need a built-in optical drive, take a look at the LIAN LI PC-Q01B case, as it seems to have better feet and can fit two 3.5in drives instead of one.

2 out of 5 eggsPoor build quality

Pros: The insides seem well machined, and stuff mounted as expected.

Cons: The build quality.
The power button is not flush (it is off by like 10 degrees), some screw holes aren't tapped very cleanly, etc.
The worst offense, though, is that the little bumps on the bottom that serve as feet had burrs on three of them. When I was hooking it up the first time, I found the burrs after noticing the massive scratches that the feet put in my table as I was shifting it around to hook up my TV. I sanded them off and it's fine now (but my table isn't). I don't expect to have to inspect for these kinds of problems when I pay extra for a Lian Li.

Other Thoughts: It is an ok case, but I expected better from Lian Li. Their quality shouldn't be going down as their price goes up.

5 out of 5 eggsTiny, plan ahead.

Pros: It's tiny.

Cons: I like the option of the slim ODD drive, but it would be great if it could be taken out without have a big hole in the front of the case. It would make it easier to route some cables above the PSU.

Other Thoughts: I love this case already. I'm using a Seasonic 600W modular power supply, and it wasn't pretty. I was unable to orient my PSU with the intake towards the CPU, because there just wasn't enough room with the cables AND the front USB/audio mounts. So far (two hours, installing Windows...), temperatures are higher than I'd like. I'm using the power supply from my old build, so I'll probably end up buying a new one.

It's not the easiest case to work on/in (it IS tiny!), but a little love and patience will get an awesome tiny build.

5 out of 5 eggsGreat Case

Pros: -Build Quality
-Small form factor
-Lightweight

Cons: -No wiring management

Other Thoughts: This is a very well made case. My components fit with ease and very easy to set up. Be warned, definitely use an m-ATX power supply. When I first had a full size ATX power supply, the temperatures for my CPU at idle was around 50-55C. There simply isn't enough room for good airflow but then again, the power supply I had didn't have a fan for intake from within the box to outside. The wiring is all over the place for ATX PSU but I didn't have modular. Things got a lot easier when I switched it out for an m-ATX. The idle temperatures are now 35C.

5 out of 5 eggsIf you want to build a tiny PC with tons of power, look no further

Pros: We prototyped a muscular business workstation for a client using this case, the idea being that its tiny size would FINALLY persuade users to stop putting their computers on the floor and instead push this tiny thing to a far corner of the cubicle desk and leave it there.

They have since bought seven more, and other customers are buying them up like hot cakes.

There are smaller ITX cases out there, but they will force performance compromises, and none are as well made as this one, with all aluminum and steel construction. The only plastic components are the side panel clips, power button, and front ports.

It includes rear brackets for both ATX and ITX power supplies and they can be installed so that the fan is oriented in either direction vertically. Be sure to use a modular PSU if you go ATX because you WON'T have room for extra cables. It is STRONGLY recommended that you use an ATX power supply with a 12-14cm fan and orient its intake toward the motherboard so it can draw heat from the CPU/RAM and out of the case, as this is all of the ventilation the case will have and there isn't much space for hot CPU's (socket 2011) to effectively cool, nor is there room for many aftermarket CPU coolers to assist with this.

Although some have complained that it is too bright for HTPC use (why didn't they save money and use an HTPC case?), I like the power and disk activity LED's being integrated into the power button. It keeps the face clean and they are perfectly bright for most lighting conditions.

With an optical drive installed, there are mounting options for two 2.5" drives or three 2.5" drives without an optical drive installed. One 3.5" drive can be installed instead of two of the 2.5" drives by removing their bracket to reveal mounting holes in the bottom. All storage drives are mounted via rubber grommets to quiet hard drive vibrations (as if you weren't going to use an SSD!).

There's even an expansion slot for installing expansion cards like discrete video if you so desire, but mind your length! You've only got about 7" and excess PSU cable length will almost certainly become an issue. I suggest cutting the PSU cables down if you have the know-how and want discrete graphics.

Did I mention it is not only really small, but flexible enough to fit LOTS of horsepower in? Potential buyers go nuts when you show them a PC that is only slightly larger than a tissue box, then push the power button and it gets to a Win7 desktop in only 10 seconds. Just name a price and the checkbooks open up!

Cons: Both side panels are snap-fit only with no place to add screws. It does come with extra clips in case they break, but we haven't seen this happen.

The USB3.0 cable for the motherboard header is actually TOO long. It must be carefully gathered or coiled between the front of the case and the header BEFORE installing the PSU, or the cable bend will push the cable out of the header. A dab of low-temp hot glue can prevent that problem.

People in the LAN party set will want discrete graphics. Everyone knows that ITX boards only have one PCIe slot, but why didn't Lian-Li consider double-height graphics cards? That second slot on the back would accommodate much better GPU's for the gaming crowd.

It's not a con because it is expected, but be aware that there is very little space between the CPU and the PSU when using an ATX PSU. Not many aftermarket coolers will fit in there. One reviewer mentioned a Noctua that does. I suppose you could use water cooling if you mounted the radiator externally, but we have always sold them with OEM coolers and stock clock speeds and customers don't usually complain about a 10 second boot time, instant file access, and instant app loads.

The lack of a reset button is disappointing, but not surprising considering the previously mentioned effort to keep the face clean. A reset button would have added clutter, and is easily replaced by a 4-second-salute on the power button.

Not everyone will like having to use a laptop-style slim optical drive and the associated adapter, but this is the cost of the diminutive size. Lian-Li makes a similar case with a 5.25" half-height bay for standard optical drives. It is just taller.

If you read my pros carefully, you will note that, with an optical drive installed, you won't be able to install a 2.5" SSD for your system and a 3.5" HDD for your data at the same time. 2.5" HDD's are widely available up to 2TB, so you decide if this is a con. 1TB SSD's are also becoming more common, rapidly deprecating this convention.

Why does nearly every case manufacturer have to emblazon the front of the case with their company name? We could silkscreen our company logo there, but having both will look crowded. They could put the brand name elsewhere that is still visible and less tech-savvy owners won't think that they own a "Lian-Li Computer"

It's not toolless. Who cares? If you don't know how to work a #2 philips you are a tool.

Other Thoughts: So how do we spec these so that we get to name our price and they still sell like crazy? The customers have some options, but they are all pretty similar:

*-Asrock FM2A85X-ITX motherboard (or Gigabyte GA-F2A85XN-WIFI if they want WiFi)
*-Choice of A8-5500 through A10-6800K APU
*-4, 8, or 16 GB of DDR3-1600 (8-8-8-24) and 32GB will be available once 16GB modules are easier to find.
*-DVD-RW, Blu-Ray, or BD-RW (typically Samsung)
*- 120GB, 240GB, 500GB, 750GB, or 1TB Samsung 840 EVO SSD (this is the REAL secret sauce. Sandforce can kiss my grits)
*-FSP 80+ Platinum 450W modular PSU
*-If they want discrete graphics, there are several Radeon HD7750 cards out there that will fit and can be adequately powered by the FSP PSU.
*-Logitech MK270 and S120 to round it out

A unit with all of the above options maxed out will boot Win7 Pro from power button to desktop in less than 10 seconds, and the people who aren't used to seeing anything but the crud at eye level in Bast Buy or Sem's will gleefully write $2500 checks and go on a waiting list to own such a tiny marvel of a power plant.

It's a shame the case is at EOL and we will have to find something else to build them with eventually.

BTW - Not one in that original customer's office has found its way to the floor yet.

5 out of 5 eggsGreat Case

Pros: This is a nice case. High quality paneling and looks great. Perfect for a small but high-end entertainment box. You can even get a low profile GFX card in it!

Cons: With a full size power supply but I was able to get all the parts in with some fussing but I bought it for its small size and features so can't complain. Make sure to get a modular power supply for this so you don't have lots of extra cables with nowhere to put them.

5 out of 5 eggsAfter you pick an ITX MB, check this out

Pros: Small
Clean
Well built

Cons: Bright power light - should be tiny led or be tunable by end user - too bright for htpc.....
Is that my only complaint - i think it is and i am right picky...

Other Thoughts: An Update:

The Noctua fit like a glove. Ultimately the system went together quite well, easier than i had hoped after seeing the Q03 case. I debated over springing for an SFX PSU but read elsewhere that having an oversized, high quality PSU in the Q03 box was a good idea; this is due to the PSU providing the main chassis fan for the case. So with an oversized PSU, it never works anywhere close to its capacity and therefore the PSU's heat v/s its fans cooling capacity leaves the PSU quite cool with its fan barely spinning up. Between the Anatec PSU and the Noctua PSU cooler the system is all but dead silent from 3' away and my temps at idle range from 38-42 C; under HTPC loads the temps bump up to 40-45 C with no additional noticeable fan noise, though i do note that speed must increase per the increase in moving air. Running Prime95 just as a safety test, temps ranged from 42-48 with the occasional spike over 50C, up to 54C, but these spikes are short lived; as these spikes did occur the fans spun up to audible for the first time since powering the system up and the temps quickly dropped back to the ~45C range with the fans dropping dropping back to near silent almost simultaneously. Following the 120 minute run of Prime95 the box was cool and silent after 3 or 4 minutes.

Final Build Specs:

-Lian Li Q03-B
-i3 3225
-xfx 6670
-Samsung 840 SSD - 120GB
-WD 2.5" HDD - 750GB
-unknown slim optical/BluRay drive
-Anatec 650w 80+ Gold PSU
-Asus p8z77-I deluxe/WD
-8GB Memory

Lessons learned for the Q03 box:

-I like the oversized, high quality PSU - allows the PSU to double as a chassis fan why remaining practically dead silent during all use other than stress testing

-the Noctua is definitely not a replacement for the radiator on your race car, but on an ITX build in a pretty small box with an SSD, 2.5" HDD, slim optical blu-ray, 6670 graphics card and an efficient PSU overkill doubling as a chassis fan, the Noctua is perfect.

-keep lots of little SATA cables around during this build - every inch of cable you dont use is better cooling in your case and i imagine that if you picked up this board space and cooling are likely to be the two items atop the priorities.

Final Thoughts:

If i hadn't stumbled into most of the parts at no cost to me, i would have built my HTPC a bit more basic; having said that, this is a sweet machine. As a long time Gigabyte builder, i have no regrets with the Asus MB. it is apparently well built, has yielded a very stable system and allowed me to have a powerhouse full of features in a case smaller than my shoe boxes.... Just wish Asus would head comments on color scheme - i could never use their color schemes building a gamer or enthusiast rig for a client, say in a HAF-XB - i would get laughed at! Quite a shame as i really like the Asus BIOS.........
