Question 1

What does PCB replacement mean for full lighting effect?

Accepted Answer

Today (11/10/25) I did some research on that since I'm going with this case myself. (Somone else can correct me if I am wrong) This is what I understand with "PCB". It's the piece(hardware) mounted in the case for the case fan lighting cables to plug in to get the built-in lighting. Since the case is offering infinity mirror lighting and many more possibilities (through the software) of lighting patterns, etc.. this needs to be changed. The "ai bot" on the Lian Li's website was saying it has to do with earlier batch of cases so it's definitely a possibility the ones today(11/10/25) won't need it but once the case is purchased the support team can verify our specific batch to see if we got the updated "PCB". I will definitely give an update once I get the case and do the "PCB" thing myself.;))
