The Dan C4-SFX is DonDan's latest and possibly greatest creation. Coming in at 13.4L, it has been in development since February, 2020. Users have been able to contribute, and DonDan has been paying attention to those contributions. This could be the penultimate SFF case, and I see it as spiritual successor to the NCASE M1. Well, at least until the Ncase M1 EVO comes out.
