Introduction

Because of the growing pupularity of the tower style sandwich layout I created the B4-SFX. This case has support for 320mm long triple slot GPUs, fits a 280mm AIO and has a volume of 12,27L.
The PSU and Motherboard I/O can be reached over the backside of the case, while the GPU I/O is accessable over the bottom. You need a angled HDMI or Displayport Adapter/Cable to connect the GPU with your monitor.

Wow @dondan, a surprise arrival to the Dan Case family.

That's a great looking and compact vertical case design!

The mesh sides look particularly good for efficient cooling.

Please don't get too distracted from getting the C4-SFX onto the market! 😉

Just posting so that I can officially say that I was one of the first people to first see this HAHAHA!
In all seriousness though, its a good looking case!

i always thought it was a crime that the chimera mach one hasn't made it to market, another banger to add to the DAN arsenal 😆

Nice! It looks good and I appreciate that the GPU I/O are directly accessible (= not routed to the back of the case), prevents compatbility issues.

Would be great, if it weren't a standing style, but this'll be cool for a lot of people as an alternative to the horrific H1, or the hard to get Meshlicious.

Convenient layout like in Meshlicious but in a smaller form factor, more space-efficient and made from premium materials, I love it.

As quite a few people will probably be building a custom loop in this case I think having mounting holes for a small pump/res combo or just a DDC pump above the GPU would be a killer feature:



EK-Quantum Kinetic combo is probably too wide (71x70mm) but 62x62mm DDC tops like Barrow/Bitspower ones should fit.

Don't like the design of the front panel though. C4-SFX's front panel is really nice and pleasing to look at, this one however looks a bit like a generic top/bottom panel that's mounted vertically (for the same reason I don't like vertically mounted horizontal cases).

Great design, I love it. If that case would have existed one or two years ago, probably I wouldn't have started to make my own cases...

Just one proposal:

the GPU I/O is accessable over the bottom. You need a angled HDMI or Displayport Adapter/Cable to connect the GPU with your monitor.

not a big deal - but for a premium case like this, I would try to integrate one DP or HDMI output at the back of the case. Something like this for example:



If someone needs to connect more than one monitor, still can use additional adapter cables.

I know my next case will be a vertical style case, and this is now on the list to choose from. I love the design, and look forward to seeing where this design goes!

The big question is should i made it with 280 AIO support in 12.2L or just 240 AIO support in 10.5L.

I vote for 280 for two reasons:
1. For custom loops, a single slim 240 isn't enough to dissipate 350W+ of heat at comfortable noise levels. For reference, 5900X + 3080 FE consume ~445W at stock. 280 rads have ~36% more surface area than 240 and can handle such load quite well. I would also make sure that 280 GTS fits in this case which is the best slim 280 rad available.
2. 140mm fans provide more airflow than their 120mm counterparts at the same noise levels (or same airflow at lower noise levels).

Completely agree on this. Sourcing a HDMI or (especially) DP cable with a sufficiently low profile 90° bend in the right direction of the right length for your setup is far from trivial. Most 90° DP cables in particular still stick quite far out from the PCIe bracket. SSUPD tries to solve this (quite poorly IMO) with a bundled angled HDMI cable. Badly due to that cable being 1m long, which would barely be enough to route along my monitor arm down to the desk, and definitely not enough to go below the desk, over to the PC, and up again - it essentially necessitates routing the cable clear across the desk. Also due to the cable being HDMI 2.0 only of course.

So with this case being smaller and having less clearance for GPU plugs (from the looks of things, at least), using an extension like what @REVOCCASES linked would be pretty much essential - I'd say one HDMI and one DP for ideal coverage of most use cases, with a pass-through hole for further connections. Of course this would raise the BOM, but hopefully not by more than $10-15 when buying in bulk.

Other than that I really like the concept though, it looks impressively dense! 280mm rad support would be a must for me.

I would say at least 280 AIO.

You may also consider to make it a bit higher to fit corsair XR5 (420 radiator) which is 450mm tall like Sligher SV590.
In this case you have plenty of room for bottom GPU I/O and won't require tall case feet.

At last I hope there is enough space (2mm) to snap in magnified dust filter under front panel.

Thanks for the great work.

The issue with these extensions is that they do not support the latest HDMI and DP versions. HDMI is limited to 2.0b and some users have reported getting only up to 1.2 speed on the DP cables. IIRC, the Velka 7 had a lot of issues with this. For a retail case, this can't be accepted imo.
