Upgrading Advise needed. E-Atx into Mid Tower?

[Grave65]

Hi,

Currently have a casing Lian Li PC-7FNW with Rampage Gene II.

Thinking of upgrading to Rampage IV BE with watercooling.

I measured the MB plate, it seems to be able to fit RIVBE.
but official specs doesn't.

Juz wanna confirm has anyone done this or retro fitted E-ATX into a ATX casing?

Any Advise for a newbie?

Maybe the motherboard can fit into Corsair 540 Air case

Yup I m considering the Cosair 540 Air case in event it doesn't fit.

Other issue is what I can do with my old cases? sell or throw it?

even if the rivbe fits, I may hv tight clearance for wirings.

seems like a dilemma...
