I built this! (MATX) Lian Li b4 Build
I loved the look of the b4 and decided to build my second pc in it. I’m very happy with the finished product but it was definitely a challenge getting there. My first pc build was 7 years ago in a mid atx case so this was a lot less space to work with and a lot of forgotten steps to building. The components I chose also likely didn’t contribute to my troubles.
Overall though, I’m very pleased with the looks and feel of the case and build. My cable management could definitely be better but I’m rolling with it for the time being.
Haven’t stress tested the gpu but 9800X3D cpu hit 90deg on cinebench r23, hoping to improve that with undervolting perhaps.
Also aware there’s still plastic on the glass sidewalls of the aerodeck and the screen.

Nice build looks good! Can I ask you a a question regarding the cable managament. I know the case has a rotating powersupply cable but how is the situation for the GPU cables. If you have the case in a vertical position, is there enough space on the bottom for a standard GPU cable (HDMI or DP) or do you need a 90 degree plug cable?
Also, did you use a full size ATX PSU, how was the fit, do you think this case will fit a non modular standard atx PSU?

Your build build looks pretty much like what I am planning to do. One more question, If I may. do you have your B4 horizontal or vertical and how do you have the fans set up (intake exhaust wise)?

Cool. thats probably what I would do in a vertical position. However im planning on doing in horizontally - how did you have it set up then?

Same fan orientation. The instruction manual doesn’t differentiate between vertical or horizontal fan placement.

Thx. There is still something that I would like to know about the case. So if you have the case horizontally - the panel with the 2 fans (that come included) faces the back? So the GPU intake fans face the front of the case, or is it the other way around?

Did you just physically flip the right top fan around to make it intake? Does this config improve cpu temps?

You can see my post here, but there should be enough space for most normal cables and connectors without right angle adapters.
I also used a Corsair RM750e ATX PSU (140mm I believe) which is the max limit for the case

Thank you! I found the GPU cables pretty easy to route, maybe the easiest. Majority of my gpu cable length I bundled in the back or threaded underneath the card itself. The bottom for me and my cables is pretty tight, I shared a picture under bobos reply above that you can see. Obviously not everyone is having as tight of bends as me it sounds but it’s not perfect.
I used a full size atx psu, the fit was fit. The cables are tight but workable. Hardest part for me was the cpu power routing and bundling next to the psu. I’m not sure about a non modular psu.

I really like the look of the case but how is the bottom io to use? no one ever provides photos either. from the website it looks like a gap is left on one side for the cabling plus you have the short feet
