Noise and Thermal Testing, Overclocked
Given the emphasis on processor cooling in Lian Li's PC-A05FN, hopefully the enclosure's unusual design will pay off with the substantially increased thermal load that the overclocked processor and RAM bring. That said, we can expect increased ambient heat in the process and with no directed airflow going towards the GeForce GTX 580, I'm at least a little concerned about the heat and noise that card may put out.
Processor temperatures wind up being excellent, and the chipset and DIMM results are also excellent, but sacrifices are made. The SSD runs hotter than almost any other enclosure we've tested (not really a concern for an SSD, but we'd be wary of using a 2.5" HDD), and the GeForce's cooler is definitely being taxed more than usual. That idle temperature is pretty much the worst we've seen, and the load temperature is mighty close.
Unfortunately, while noise in the PC-A05FN is good, it's not great. While the processor stays cool enough, that GTX 580 is roasting. It's among the quieter enclosures we've tested under load, but at idle the GTX 580's fan is already working harder than we'd like.

Lian-Li cases always seem to have too large dimensions. I know for this example the depth is because of the front-mounted PSU and the height is short for being able to fit a full ATX motherboard, but this observation holds for many Lian-Li cases. Theyt always seem to be rediculous in one dimension which throws off much of the appeal.What I would love to see is the same case in an mATX version. Place the PSU below or above the motherboard and reduce the excessive length from 20" to about 16". That would be a nice-looking and functional mATX case.

What is the point of reviewing a product assembled with components that it is clearly not designed to handle? Your testbed is obviously not a one-size-fits all proposition either. You cannot pass judgement on a particular design when you start off deviating from that design. How about a re-review assembled with the components it is designed for?JarredWalton - Thursday, December 8, 2011 - link
If we take a lesser setup (maybe a 6870 GPU, a smaller PSU, and change out the CPU while we're at it), power and heat and noise all go down. That doesn't necessarily tell us much about cases other than that lower end equipment doesn't require as much cooling. Our rationale with the test configuration was to put together a reasonably high-end setup without going overkill. The GTX 580 is a fast GPU and more than what a lot of users need, but at the same time I know I wasn't happy with my single HD 5870 and I'm doing much better with a 580.Even without testing lower end hardware, the inclusion of both stock and overclocked testing gives us a good idea of how a solution scales. The idle noise, temps, and power will only drop marginally while load will be somewhere in between. The PSU will have better clearance, which we don't even need to test. Basically, the point of a standardized testbed is exactly that: to have a standard. Changing the standard would change the results, but you can compare the cases regardless. It doesn't "invalidate" anything.

Sorry, Jarred, I beg to differ. What a reviewer has to remember is that the perception of the READER of the review is what is important. A READER looks at a review to decide if a product performs AS IT IS DESIGNED and FOR THE PURPOSE IT IS DESIGNED; not for a comparison of how well it works with obviously above-the-design-level components.No computer builder or enthusiast in their right mind is going to consider stuffing a case such as this with components the likes of the test bed used. To do so to satisfy your own curiosity is one thing; to consider it a "review" of the product is quite a stretch and lacks VALIDITY.
That's my story and I am sticking to it!

Except that knowing that it CAN handle these components (albeit with work) suggests that it should perform much better with a component selection much more appropriate to it. I've given you the information you need by going above it.And as far as I'm concerned, the individual perceptions of the readers (which can vary wildly) isn't important to me. What is important is producing a review that is fair, understands what the hardware being reviewed is intended for, and as factual as possible. I can't tell everyone what they want to know, but I can tell most of you what you NEED to know.

This case is one of the smallest ATX cases you can buy, and you can really fit a whole lot in there if you do some research beforehand. Of course it's not for everyone, but then again, not everyone is a case enthusiast.With regard to GPUs: you can mount any GPU you want to in there if you remove the hard drive bay. I am using a 11.5" Gigabyte GTX 570 Windforce without any issues. I have a DVD drive, 3.5" HDD, and 2.5" SSD in the 5.25" bays.
All of your concerns about GPU cooling would be alleviated if Lian Li included a side intake by default. I cut a side intake on my A05NB (the last revision of this case, with the inverted design), and GPU temperatures are excellent.
Lastly, I wish Lian Li didn't ditch the inverted ATX design with this new revision. The older inverted design had a number of benefits, such as:
1) No chance of PSU blocking any SATA ports
2) Intake fan at the rear is placed lower than exhaust fan in the front, allowing hot air to rise
3) Room for a radiator at the top or bottom of the case.
4) If you have a liquid cooling system on the CPU and it leaks, it won't leak onto the GPU because the GPU is located above the CPU in the A05NB.

The old design resulted is some truly beautiful water-cooled mods - I only wish I was half as talented.The inverted ATX design worked really well.
Lian Li go back to the old design but with the following changes:
1. More room behind the motherboard tray
2. Bit more space (as per Fractal Arc mini) up top so radiator fits comfortably
3. I like the front mounted PSU concept but experiment with it being across width of case not the normal way, there are two ways of doing that, intake fan on bottom or intake fan facing front of case. Big advantages are, much cleaner cable routing and much more space at bottom of case (ideal for pumps, SSDs
4. Not sure we really need 2x 5.1/4 and a 3.5 external bay. Any chance of cutting one out and increasing size of front fan (nice location for front mounted radiator)

Used it on 3 or 4 builds. Very nice case. It is a bit thin for my liking. However, I wouldn't hesitate to use it on my own rig, if I didn't have 5 HDDs, 2 optical drives and 4 expansion cards in the mobo.Death666Angel - Thursday, December 8, 2011 - link
I have to say that reading the reviews of small enclousures on AT is always something. You manage to point out the difficulties of those cases, but i often get the feeling that Most people who choose a small case for potent hardware already know the limitations anderen build around them. still, great to see reviews of more normal (read : sub-150) cases, since i dont think you need to spend a lot on a case even if you use expensive components . :-)Death666Angel - Thursday, December 8, 2011 - link
Typing on a smartphone with German dictionary in the background messes things up. Hope it's still readable. :D
