Are actually 6 (or 5) best to look at nzxt website. I bought it but now I don't know because I replaced everything with 140mm rgb fans.

Yes, the "i" version of this enclosure has an integrated fan controller, which can of course be controlled with CAM. 👍

You can see here how they imagine it: https://sta3-nzxtcorporation.netdna-ssl.com/uploads/download/attachment/770/H710i_H710-manual-070720-ver10-web.pdf Three are safe, the fourth seems a bit optimistic to me because it competes with the PSU cables? It depends on how much you want it.

Yes

Yes.

I ordered it 3 weeks ago. Fans were already installed in my case. 1x40mm in the back, 3x120mm in the front.

No, it is not. There are some improvements in the h710i, such as the way the disc is closed. In the h710i, the disc is closed with only one screw and not with 4.

No, three won't go. Probably only 2 will go. But 3 120mm would go

Yes, this case can accommodate CPU coolers up to 185mm high. The dark rock pro4 is 162.8.

The i version also includes a built-in LED strip and a vertical GPU mount.

Unfortunately, we currently have no information about when the item will be available again and when we will be able to deliver it. The supplier himself is still waiting for a subsequent delivery from the manufacturer and for this reason he had to set the delivery date to unknown. As soon as something changes in this regard, we will post it here. Sorry.
