Hi all!

I wanted to share my last build. The task was to fit my components (which I already had on hand) into a small case with sufficient cooling for travel.
I would love to buy a T1, but at the time of assembly it was not on sale. Therefore, the choice fell on Lian Li A4-H2O 11 liters.

Since I have a hot processor and video card, I need to assemble it with water cooling. But it turned out to be impossible to fit such components into an 11-liter case without modification. Therefore, I want to share my modification of the case and some components.
During the build process I had no luck with EK's DDC pumps. 2 pieces burned out. It was very sad. Therefore, the final photos included a pump from a Chinese manufacturer.

To cool the video card, I used a HEATKILLER V. However, to fit it in such a tight space, I modified it (see photos). I have not seen such a modification on the Internet. I hope this will be useful to you.
The body modification was also used. The back panel has been completely replaced.

This is my first project working with water cooling. I experimented with installing rubber tubes, acrylic ones, and of course it would be very cool to install EK nickel tubes. But when I put the project together with acrylic and it worked, I was very surprised at how heavy it was! It's just a heavy brick. I was naive and wanted to carry it in my bag to work outside the home).

For traveling and wearing every day, even just from room to room, this option was not suitable.
I hope my experience will be useful to you, friends, thank you for your attention! Have a nice day!

I did the assembly in the spring of 2024. And since it turned out to be heavy, I started a new project (by the way, I’ve already finished it, I’ll write about it in the next post. The case that I developed myself, for the 4070TiSuper - 3.9 liters.)

Holy moly. That's really impressive!

is the 2nd radiator fanless?

oh mb lol

Is the side radiator just ramming air into the graphics card block? How much clearance is there for airflow?

it was planned that the fans would blow air out of the case. but you can see in the photo that I oriented them incorrectly🤣 but even in this case there were no problems.

#

I made the photo brighter so that the distance from the fans to the video card can be seen

good to see there is some clearance

Having looked at this again, that fitting run between the gpu block and the external fitting junction looks pristine.
Did the stars simply align for that geometry, or what?

sry i mean cpu block

Oh I am not watercooling, I was just impressed how compact the runs are

ahaha. I thought there was little space. But it turned out that there was still a lot of empty space inside. I was even upset because I thought it was a minimal case. So I decided to make the case myself for the next project, so that it would be as dense as possible, this is the next project. air cooled. All that remains is to do a photo shoot and I will post it here. I will be glad for support)

@sand wadi how did you mount the PSU? Just drilling some holes or create a custom bracket? This is actually one of my biggest griefs with the A4-H2O: The totally inflexible, awful PSU mounting bracket.
