I doubt this would work well, tbh. Running the rads passively like that means it's wholly dependent on pressurizing the case to get air flowing through them, but you'll be losing a lot of airflow through the PSU.Hey dondan,
I like the new design language but I think the new case is too similar to the M1, not significantly smaller in footprint (which matters most) and has less to offer. So, I'm afraid it would have a hard time at Kickstarter.
I think you should consider a bolder approach and differentiate your new case significantly from what's available (that's how A4 became a success). Now open your mind and consider this layout:
Sketchfab link: 9L Dual AIO by theGryphon

View attachment 37754
- The model here includes two 120mm AIOs to cool both the CPU and the GPU.
- Only the front and the top are (fully) perforated, all other sides (including the back) are solid.
- The GPU is 300mm long.
- As you can see, it's rotated 90 degrees wrt the motherboard, so a flexible riser as pictured above is required. As you know, Corsair One uses a similar 90 degree riser.
- Also note that the hot side of the GPU is facing the outer panel, not the motherboard.
- There is a net 72mm clearance between a regular 2-slot GPU and the motherboard surface.
- There is also 13mm clearance between a 2-slot GPU and the PSU.
- The fans on top are 92x25. They are the only fans in this configuration which requires them to blow out for negative air pressure.
- The reason these fans are used instead of 120mm fans on the radiator is this: The GPU cables on top would already require this height for the case. Now that height is efficiently used for both GPU cables and the 92mm fans. This saves precious volume and footprint (which is the main design goal) for the case.
- Alternative configurations:
- A 240mm AIO cooler for the CPU with a 2.5-slot GPU with axial fans. 92mm fans are blowing out for negative air pressure.
- A 120mm AIO cooler (at the top) for a 2-slot GPU along with a 120mm fan (blowing in) on the front and a CPU heatsink with up to 70mm height measured from the motherboard surface. 92mm fans also blowing in for a positive air pressure.
- No AIOs, instead two 120mm fans in the front blowing in, and a CPU heatsink with up to 70mm height measured from the motherboard surface. A 3.5" drive may be used on top in place of the 92mm fans (while this would obviously lower the cooling potential for the case, some people may want to use the case with not-so high-end components).
- In all configurations, a short GPU would enable using a 3.5" drive (or multiple 2.5" drives) in front of the PSU.
- Case dimensions are 125 (width) x 210 (depth) x 360 (height) = 9.45 litres.
Additional benefits of this design:
- No need for internal cables
- ... except for an internal HDMI cable to enable VR devices from the front.
A correction: you mean USB Type C, which is the physical connector. USB 3.1 is the electrical/signal interface standard, that will operate with any connector.Aesthetically, I would suggest that both front top USB ports be USB 3.1.
I'm doubtful whether the slim fan / bottom radiator position will prove practical fro most buyers. I've had to extensively mod my M1 to get the bottom radiator position to work to a level that I'm comfortable with, and I'd like to think I'm already quite clear with my expectations ( Priority for aesthetics over performance in particular).
With a full thickness 25mm fan it may be borderline but most folk who water cool expect silly low temperatures even if it doesn't give them any practical benefit.
The top position however will be perfect. Even if you were to focus on a top position only with a cleaner design I'm sure you'd be on to a winner.

Thank you for your idea, but I don't like your layout because of following reasons:
- I don't like skyscraper style cases
- Your design requires a riser cable with complicated bend so I have to use 3M and this will result in long production time + high price
- Your design requires special display port and HDMI extensions that will be not up to day some years ago and will increase the price
- Two 92mm fans have to spin fast and loud to generates enough pressure
I am very happy with my current design, so changing it is not an option. Optimizations are possible as long as they refer to my design.
I doubt this would work well, tbh. Running the rads passively like that means it's wholly dependent on pressurizing the case to get air flowing through them, but you'll be losing a lot of airflow through the PSU.
I'm assuming this is partly inspired by the Corsair One, but keep in mind the Corsair One uses dual 240 rads, not 120. Those aren't fully passive either - they utilize the GPU blower and PSU fan to draw air through a section of the fins.
Sorry, my mistake. I read a bunch of posts and then came back to respond to yours without re-reading it, and I think I got it confused with another post in the process. So, negative pressure then.I think you misunderstood the intended airflow. The top fans are and should be in the orientation to create negative airflow, which means they are working together with the PSU fan, not against it.
Now that I go back and look at it, the PSU in the Corsair One pulls air from the backside of the GPU and motherboard, and ejects it directly into the path of the top exhaust fan, to be immediately blown out the top. So in effect, it's not really dumping any hot air in the case.True that Corsair One inspired me and that it uses 240mm rads, not 120mm. However,
- It has only one 140mm fan to actually exhaust the hot air from the case.
- It is much more cramped so the airflow is much more restricted. Radiators are pretty much blocked by other components.
- Its PSU fan is not contributing anything. Let alone that, it bugs the internal airflow and dumps hot air inside the case.
I would argue the opposite. When you don't have a lot of airflow, you want more surface area to compensate, not less.Radiator size becomes relevant (and increasingly significant) only with sufficient airflow. Plus, its radiators are of very slim type, so there is that too.
Model Size RPM dB/A m³/h mm H2O
NF-A14 PWM 140x140x25 1500 24,6 140,2 2,08
NF-A9 PWM 92x92x25 2000 22,8 78,9 2,28

Also, 2x 92mm fans do not necessarily produce more airflow than a single 140mm. Take these Noctua fans, for example:
Code:Model Size RPM dB/A m³/h mm H2O NF-A14 PWM 140x140x25 1500 24,6 140,2 2,08 NF-A9 PWM 92x92x25 2000 22,8 78,9 2,28
Two 92mm fans move about the same amount of air as a single 140mm (different speeds, but similar noise levels - although pitch is likely more annoying on the smaller fans).
You have 60mm
Today I ordered a Arctic Accelo Hybrid-III *GPU AiO) to get the real length of Asetek based 120mm radiators. It is the same for EVGA and NZXT. If it is true the length is lower or equal 152mm I will add cutouts to the middle plate so the case will support 2x120mm radiators![]()

Changing to complete USB3.1 will be only supported by one premium priced ITX board. I don't want to limit the usage of I/O to a single mITX board.Thank you for your idea, but I don't like your layout because of following reasons:

JackGLemmon:
I am not interested in optimization a already made design from Lian Li.
Quartz-1:
And as I mentioned just flip the case and it will be on top. The U-Frame side panel will protect it.
Changing the position of Audio and USB ports on top will make flipping the case impossible. It is not possible that the card "adrift" or sag down because it is clipped in the PCIe socket holder and screwed to the case. Also the riser is screwed to the chassis.
If I can use 2 120mm AIO coolers with them mounted on the top then this will be an instant pledge/purchase for me! The A4 will go to the closet for use at a later date.
Thank you for being part of my poll. Here is the result:
![]()
The result is very clear! The most participants like to use a radiator with a thickness of 28-30mm in combination with a 120mm fan with a thickness of 25mm. Like I handled it with the A4-SFX project I want to give you the chance to have influence on the final product.Therefore I increased the height of the radiator/fan chamber to 55mm. To stay under 10l I made the hardware chamber 2mm smaller. So the total case dimensions are: 127,5 x 242 x 323,6mm (W x H x D) = 9,9l
The new cooling chamber allows the following radiator configurations:
· 22mm thick radiator + 25mm fan
· 27mm thick radiator + 25mm fan
· 30mm thick radiator + 25mm fan
· 38mm thick radiator + 16mm fan
· 40mm thick radiator + 15mm fan
I am wondering that only 7% of the participants plan to use air cooling. Maybe the name of the product suggest that you only can use water cooling or the poll image in the threads looks like a only water cooling related poll.
Furthermore I never thought that 48% plan to install a custom water cooling solution. Because at the current state it isn’t clear that a custom pump will fit.
I did a bit of research to identify all custom water cooling radiators that will fit:
26-30mm thickness class:
· Aqua Computer Airplex Pro 240
· Bitspower Leviathan Slim 240
· EK Water Blocks EK-CoolStream SE 240
· MagiCool 240 G2 Slim Radiator
· MagiCool 240D
· MagiCool Xflow Copper Radiator II
30-40mm thickness class:
· EK Water Blocks EK-CoolStream PE 240
· Swiftech MCR220 Quiet Power
· XSPC AX240
· XSPC EX240
· XSPC EX240 Crossflow V1/V2
· XSPC EX240 Multiport
Thank you for your help

The Apogee Drive II with fittings is >70mm tall, so that's not an option. Rads with integrated pumps are also way too big. A standalone DDC or other small pump might fit under the PSU, but it'll be tight. Two options that look like they might work:Custom vs AIO - a DDC pump really doesn't take up a ton of space. I actually ended up with plenty of empty space under my GPU in my NCase M1 build, thanks to using an integrated pump / CPU block and no reservoir (and I really can't get over how cold it runs, sorry guys I know I keep throwing it out there but hitting 50 degrees under full load for hours of gaming is just awesome - and it idles in the high 30s to low 40s). So, I would think that as long as there is room for a Swiftech Apogee Drive II or similar on the CPU, or room for a radiator w/ integrated pump / GPU block w/ integrated pump, there will be some very creative, tightly packed custom loops with your case and I can't wait to see what people do with it.
Even with 90° swivel fittings? Also when I looked a while ago the apogee was impossible to buy have they started making it again?The Apogee Drive II with fittings is >70mm tall, so that's not an option. Rads with integrated pumps are also way too big. A standalone DDC or other small pump might fit under the PSU, but it'll be tight. Two options that look like they might work:
Of these, the Eiswolf seems like the best bet. The Celsius' rad might be a little thick or long, and probably isn't an ideal candidate.
Regardless of which of these pump options are used, it seems a stretch to imagine there would be room for a res.
Today I meassured the Arctic Hybrid III that use a 120mm standard Asetek radiator. It looks like two 120mm radiatirs will be 300mm in length. So you will be able to use one 120mm AiO for CPU and the second one for GPU![]()
Ah, very cool. Might sell my A4 for the C4 then. Who knows?Maybe May 2018.
Those fins are not necessary, they aren't on a standard DCC pump. Easily they could be reduced in height. The problem would likely be routing the tubing without hitting anything.Ah yeah crap. Too tall. Hmmmmm well I mean worst case you mount the pump outside the case but I do like the look of that Eiswolf...I suppose mounting point for a DDC pump is one more thing to consider in the design since there's a significant number of people planning on doing a custom loop in this case.
edit - Dan lists the max CPU cooler height as 60mm. Even without the fittings, per the following link the Swiftech Apogee Drive II is 61.5mm tall.
