@x01 - I have an ASUS Republic of Gamers Strix Z390-I and it does not fit in Velka 5
... unfortunately - I am trying to fit it in the Velka 3 but I do not have a flex compatible power supply (I thought I have one but seems it doesn't have a CPU power
connector and my cables are too short - I tried to repurpuse a flex PSU) so I need to buy a new flex PSU.
later edit: I just now verified the incompatibilities even with Velka 3:
1. the motherboard is still hitting the front part of the case when installed (you need to unscrew the top back screw (and slide the front part between the stand off and the back part of the case - not a huge deal but still
2. the cpu mounting screws (Noctua NH-L9i) are hitting the PCIe connector of the extension cable, not allowing for the extension cable to be fixed-in/secured intro place with the included set of screws, I used longer ones ... unfortunately this makes the GPU a little bit flimsy (I didn't figure it out yet how to overcome this issue, maybe some washers again can save the day)
3. due to issue nr 2 corroborated with a possible width issue of my gpu, the gpu fan was hitting/scratching against the side panel (I had to use 1mm washers to clear it) not sure if this can be considered a "fix" but is a "for now" solution.
My reco: DO NOT USE the Z390i ROG strix from ASUS to build in any of V3 or V5 ... too much of a headache.
Is there a list of compatible hardware with Velka cases ? seems to be a little more "restrictive" compared with other SFF's
PS:
@VELKASE Michael - I hope you will consider the above as constructive criticism not bashing the case at all
