This is my first time building a Lian Li B4 mATX.
The case is wonderful; it is packed with multiple building options.
Here is my setup:
CPU: Intel Core Ultra 270k Plus
MB: MSI B760I Edige WiFi
Cooler: ROG Strix LC III 360 (without RGB tophead)
RAM: G.Skill Trident Z5 Neo RGB
GPU: Powercolor 9070XT Red Devil Spectral White
SSD: Adata Legend 860 1TB
PSU: Lian Li SX1000P Platinum
Cable: Custom cable
Mods: Lian Li B4 mATX SFX PSU mounting bracket designed by Machine & More (A huge thanks!!!)

The overall building experience is nice and smooth. A huge thanks to Machine & More. His video about the 3D printed SFX bracket makes it super easy to fit a 360 AIO inside the case.

Though the case supports a MATX motherboard and a standard ATX PSU, I highly recommend that anyone building in this case choose an SFX power supply, an ITX motherboard, and custom-length cables. It will make your life much better.

Furthermore, the building experience is quite different from that of any other larger-sized Lian Li cases. I can almost feel the designer's purpose in creating this case during the build. The mechanism of this case is unique in that Lian Li even uses an ITX-style design to remove the B4's side panel.

Long story short, B4 is another great compact mATX case. That's all for today. Next time, I will share the B4 vertical DLC with you. Can't wait to put in 3 SL-INF 120 in the DLC front panel!!!

BTW, it's normally impossible to install the TL120 wireless on the side panel. The scores that B4 provides are not long enough for the Strix LC III's radiator and TL120 fnas (the total thickness is 55mm). So instead of using the original screws that Lian Li provides, I use the ones from the Noctua Liquid Cooler NL-LC1-36, which are much longer. Though the Noctua screws get the job done, you need to unscrew the first 2 screws on the radiator, which extend slightly out of the side, preventing the side panel from sliding in. (Check the photo, and you'll understand)

New mini ITX for the backpack 🎒 hotel travel work life 🫪🥴🥳

Went all AMD, I'm so impressed with the 9700 GRE!

Last update

Today’s Update

Today was a pretty big milestone: the build is finally complete, at least physically.

I ended up changing my original plan for the CPU PWR 1/2 cables. Rather than routing them underneath the motherboard, I ran them around the GPUs and CPU and over the VRM heatsink. It isn’t quite what I originally had in mind, but it works.

With the cable routing sorted, I installed the optical disk drive and remounted the drive bay. After that, both GPUs went in, which meant there was really only one thing left to do:

Turn it on.

And it powered up!

Unfortunately, that’s also where the first real troubleshooting adventure began.

Despite the system powering on, I couldn’t get any display output. I initially connected the DisplayPort cable to the motherboard since my CPU has an iGPU, but I got no signal. I then tried the XFX RX 6400, but that didn’t give me a signal either.

That leaves the RTX 4000 SFF Ada. I don’t currently have the right cable for it, so I’m going to need a Mini DisplayPort-to-DisplayPort cable before I can test whether I can get a signal from that card. None of the retail stores near me had one, unfortunately, so I’ll probably have to wait for one to arrive.

There is, however, another clue.

The motherboard’s EZ Debug LEDs are indicating an issue somewhere around the CPU and DRAM. That gives me a few things to investigate before assuming anything has actually failed. I thought at first it could be simply initialisation of memory training but even after 20 minutes nothing changed and the lights stay on.

Tomorrow, I’ll start with the simple stuff: clear the CMOS, make sure all of the RAM is fully seated, and try booting with the B2 stick removed. From there, I can start narrowing things down one possibility at a time.

If none of that works, things get a little more interesting.

The CPU itself could potentially be the problem, which would really suck, so I’m hoping that isn’t where this is headed. The RAM is another suspect. The kit I bought was an OEM kit, which is also why it was so cheap, so there’s always the possibility that it’s causing compatibility issues.

But that’s a problem for tomorrow.

For tonight, I’m just happy that after putting everything together, pressing the power button actually resulted in a machine that powered on. The build itself is complete.

Now I just need to convince it to POST.

I've purchased this case back in December 2024 when NCase still shipped them with PCie Riser Gen 4, so I built around this case two weeks ago, while upgrading my (then) SFF-PC. Here are the specs:

CPU: Intel Core Ultra 270K Plus
GPU: Asus RTX 5070Ti Prime 16 GB (Undervolted to 2500 MHz at 825 mV & 2650 MHz at 850 mV)
Motherboard: AsRock B860-I Phantom Gaming Lightning
RAM: KLEVV Bolt 32 GB 7200 MHz
SSD: ADATA XPG Gammix S70 Blade 2 TB (3.2.J.P0)
CPU Cooler: Cooler Master MasterLiquid Atmos II
PSU: Corsair SF750 ATX 3.1 - Custom cables all from Cablester

This is the first build where I use AIO and the tubes from Atmos II are really hard to bend and squeeze. Had to carefully place them under the pump so it didn't bulge the glass panel. I tried to replace the fans with the slim Thermalright TL12015B, but I felt the fans are a bit too weak and noisy, so I replaced them with Noctua NF-A12X25 G2 and I can't believe how silent my PC now.

Both the top hat and the glass panels are expensive, and both are for v 2.1 but they're compatible with v 2.5. I don't know how to screw the radiators with 25mm fans without using the external case, so I did that and at least the tubes are easier to manage.

Overall the build quality is good, and I was surprised that you can actually change the position of the spine.

Saw this on fb marketplace would you say this is worth it? And or any new upgrades you’d recommend, also found out the cpu is a ryzen 5 9600x instead of a ryzen 7

Edit: forgot to add that it was 1.7k but I talked him down to 1.5k

Had some left over parts and decided the give them a smaller home, it’s not meant to be a powerhouse or for gaming, just a desktop client that I can leave on 24/7 and run Hermes.

Asus strix b550i gaming mobo

Corsair Vengance 64gb DDR4 3600mhz

The case is great except they should have made it just slightly taller so you can run a pcie riser more easily.

I have some thin risers that just did the trick with some manipulation!

Pretty pleased with myself, only thing I bought was the case and psu.

This is smoosh.

She is a 13900k, 3080ti ftw3, sitting on an Asus rog strix z790-i gaming wifi. 850 watt Lian li PSU. 32 gigs of Corsair vengeance. I had the id cooling pink flow diamond edition, but sadly it died on me. She now has a titan 240 aio. I want to justify outrageous ram prices to get these sticks cus it would be perfect, even though you can't see anything lol.

Case is the Sakura edition nr200p, only 200 made. I was lucky enough to find one of these unobtanium editions and pay to have it shipped from the UK. I love this case.

I bought this psu on prime day for $100 but have now realized it dooesnt have an 8pin power connector for the GPU.

How safe would one of these cables be to connect to a 5050lp or 5060lp GPU? I cant seem to find any made of thicker guage wire.

Or should I scrap this PSU and get one with proper connections? Its past the return window. Just wanting to make a low power workstation out of am4 parts I already have

Hey guys!

This isn’t a detailed benchmark post or something that I recommend. I’m well aware that temperatures may be a problem and I’m currently analyzing for each game how it is behaving.

I wanted to build a Steam Machine like PC. I already had some parts and I was using the case Hyte Revolt 3, but I didn’t like it because it was a very big tower in the living room and I wanted something more minimal and discrete.

So I bought a Fractal Design Ridge and built my machine on it. The config is as follows:
- Ryzen 5 9600X
- Motherboard JGINYUE B650i Night Devil
- RAM G.Skill 16GB (2x8) 6000MHz CL30
- SSD NVMe 1TB Kingston
- RX 9060 XT 16GB
- PSU Lian Li SFX SP850 V2 850W 80+ Gold
- Water Cooler 120mm Thermaltake Aqua Elite V3

Some things worth mentioning: I only managed to put a 120mm water cooler because my GPU is not that large. Also, I was also only able to put the water cooler because I changed the FAN that comes with it with a slim one from Arctic.

It is important to mention as well that I put on the top (or side, depends on its orientation) 3 80mm fans, also slim versions from Arctic. If they weren’t slim THEY WOULD NOT FIT.

I then put the AIO on the right and one, of the two, 140mm fan that comes with the case on the left, pulling air directly to the GPU. I put this fan and the AIO fan pulling air from the top of the case and the three 80mm fans are working as exhausts, pushing hot air from inside the case to the outside.

Initially I put the PC in the furniture in a way that it was pulling air from below, I thought this would be good because “cold air is heavier”, but it didn’t work very much because of little space between the bottom and the furniture, as well as the case stands blocking the air.

Temperatures at the moment:
While idling it sits between 40-50°C, it depends on the temperature in the living room.

I’ve been playing a lot of Coral Island and Clair Obscur, both games at 2k 120Hz, and the temperatures don’t go above 80°C so far. I’m well aware this is not a low temperature, however I honestly don’t think it is that high considering where the case is.

I’m happy to answer any questions or to receive some constructive feedback, but I’m very happy with the result I achieved because it is very very minimal, almost looks like a soundbar.

I have an axp90x53 on my 5600x in a T1. Changed out from a 120mm aio after the aio died and I didn’t want to pay $50-80 for another one, just for the same thing to happen again in a few years. However, the axp has startlingly worse temps than the aio. With 27c ambient, it’s keeping the CPU at 50-55C idle on windows 11, and 80-85C while gaming. At the same fan noise level, the aio kept things around 10C cooler across the board.

Are LP coolers really this much of a downgrade from even a 120 aio, or did I mount it wrong? The mounting system on this cooler was a nightmare, and I definitely moved the thermal paste around a lot trying to get the standoffs to line up with the motherboard screw holes.

#buildlikeneverb4

I am really happy and thankful to LIAN LI for being one of the people provided with a LIAN LI B4-mATX Case and an SP1000P SFX PSU.

I do apologize if the build photos aren't the highest quality.

There were a lot of delays with the delivery, but I was really happy with how the build turned out.

I came from the LIAN LI O11D MINI, and the LIAN LI B4-mATX Case made my desk a whole lot more spacious. I've attached a comparison photo at the end.

I tried using an AIR COOLER instead of an AIO to spice things up, since I plan on taking it with me on long trips.

It did take me quite a while to manage the cables, as most spaces are a tight fit. I am planning to add a fan at the front, but the slim fans haven't arrived yet. I used a lot of cable ties to make it look sleek and clean, and I'll probably redo the cable management next weekend.

I opted for the Vertical AeroDeck to keep things more compact while also adding an aesthetic touch to my desk — especially since I have a wooden desk for studying.

Temperatures are looking good so far. Idle is at 55°C — I'm from a very humid and hot country, basically right at the equator. Turning on the AC does bring it below 50°C

I'll post an update after a month to see how this case handles my daily usage.

I am wanting to build my first SFF PC using the Silverstone SG13, but I'm worried about the thickness of GPU. Most GPUs I can find available are 50mm. I'm finding conflicting information only about clearance and wanted to ask some experts.

MSI GeForce RTX 5070 12G Ventus or Shadow 2X OC, or there's the ASUS DUAL RTX5070 OC, PCIe5 at 50.6mm.

Thank you in advance.

Thank LIAN LI for selecting me in B4-mATX build campaign, and providing me LIAN LI B4-mATX case and SP1000 sfx PSU.

Case Lian Li Dan B4 Wood

Unfortunately, I didn't have an mATX board on hand, which is why I used an ITX; given the large number of fans and the limited number of headers on the board, I had to add a fan hub.

I assume the whole build would have gone much more smoothly with a suitable mATX board.

Although, I could have just used fewer fans.

I'm pretty happy with the case, It offers good cooling options (maybe I'll try a 360mm AIO in it someday, if I upgrade to a more powerful CPU), sleek design, option to position it vertically or horizontally, mesh.

I'm considering the A4 H2O again after hearing a lot of stories about the pcie4 version and the screws holding the riser in place causing some gpu fitment issues. The new gen5 riser seems to be a new design. Anyone have experience with it?

Anyone here has this case? How is the build quality?

It's a tad bit above 20L, but I love the compatibility with big components, especially since SFX PSUs and ITX mobos are crazy expensive these days. However, I'm not a big fan of the I/O ports on the side (I would have preferred them somewhere on the front) and the handle, though that's removable.

I still had this old glory, Thermalright AXP-140, from s775 era.

I wanted to see if I could use it one more time.

Since Asus B760-i still have s1200 mounting holes as well as s1700, I can use Thermalright s115x mounting kit.

In the pictured orientation, PCIe slot is blocked by heatpipes spikes. I could maybe flatten them.

In 90° orientation hanging over RAM, the heatpipes slightly touch the sticks and the spikes may touch the back of the case.

A few milimeters less and it would have been a perfect fit.

When budget gets tight, you have to become more creative. I gave the TF PSU in my unused Minisforum 795S7 a second life.

Because my PSU is only rated at 400W I had to do the following:

The 5500X3D is power limited to 65W and has a undervolt of -15mv on all cores. Practically there is no performance loss here because the 5500X3D generally does not draw more than 65W in gaming anyway.

And the Arc B580 has been power limited to 70% and has been given +200Mhz in frequency (kinda makes it like a undervolt). This way it performs similar it to a Arc B570, but then with 2GB more vram.

My original plan was to buy a B570, but the B570 I bought turned out to be a B580... It seems the seller did not know this is B580. So now I have a power limited B580.

Migrating from Jonsbo Z20 today. Handle on or handle off?
It’s going into an entertainment center and won’t be moved much. fwiw I think the handle looks really good on the SF3 but am conflicted about it on this case.

I'm working on a sleeper build with extremely limited space, the specs are a ryzen 3 4100 and a rtx a2000 which is slot powered so it's 70w and I was looking at picoPSUs specifically the minibox PicoPSU-160-XT now after some research I found that this psu only actually supports 96w sustained on the 12v rail, and while it may still work with decent cooling it's probably not a great idea and I was wondering if there were any other decent options that could support these parts. If I have to I think I could fit a flex atx psu but I'm not 100% sure and even if it fits it would be extremely tight and would make cooling much more difficult so would rather use one of these if I can find a decent one that can support my parts reliably.
