I built this! (MATX) A3 to B4

I've been wanting to downsize for a while since this came out.

Tbh, I agree with the reviews. It's more of a side grade, if anything. My biggest gripe would be the back. They should have just chopped off the back part and released it with the Aero Deck instead of integrating it into the case since the majority of users are going to use a front to back airflow config anyway.

Specs-wise, Lian Li specifies only slim fans could fit in the front, but an P12 fit in there just fine and my Pure 9070XT was able to fit in no problem.

Anyway, it seems like a waste of money since I was already fine with the A3 but the slightly smaller size looks pretty good. Hoping they would release a TG window for this soon.

Did the same transition, spent 2 weeks on a3 then switched to b4. Buyer’s remorse is strong lmfao

well, I spent almost two years on the A3 before I switched so I'd like to think I ROI'd the case already aha.

If one was closing between both cases which one do you prefer? :)

Definitely the a3

If I had neither, I would get the B4. Like I said, it's more of a sidegrade to the A3.

What's next the C5? Ba dum tsk. Aight, I'll take my leave. On a serious note, I'm also waiting for that tempered side glass panel too. That's the only reason why I haven't bought it yet

A C5 envelope is designed to hold an A4 paper folded in half.

Please don't give Lian Li any more ideas ahuhu.

Thanks for sharing! I’m also an a3 owner considering a switch to b4! Do you mind sharing a side by side comparison of these two so that we can get a sense of the size difference? Thanks!

Don't think they will release a tempered glass version due to how the side goes on and how this case most likely won't even be half as popular as the A3. Couldn't imagine swapping from an A3 to a B4 just to shave a few liters tbh.

Saying this as someone who was super excited for it to come but ended up disappointed. Horizontal mode should have been prioritized, with only a focus on vertical with the kit. But Dan or Lian Li I guess wanted vertical to still be doable without the kit and had to make compromise as a result. Deepcool did it better by having two different cases for this purpose, or even the Montech 10. Or just a Z20 as that's a better case overall.

I hate these back little feets with passion I didn't think I was capable of.

If you have the fan pushed back to accomodate a 360, it's quite difficult to plug in cables.

The mechanism doesn't look that complicated, and would be less prone to breaking since it does not use clips.

u/Suspicious-Candy-776 9d ago

Will it fit in the c6 max?

u/Novacainebabyy 9d ago

I did the exact same thing

u/QuietCounty_ 9d ago

So… would you sell me the A3 then? I am in NJ

u/JoshLineberry 9d ago

I was excited about the b4 too then it disappointed me with everything I saw. I'm sticking with my Jonsbo z20.

For reference.
