RTX 3090 and bit Fenix Ronin

[bigmike20vt]

In a moment of madness I just bought a rtx 3090 after getting fed up going for 3080.
It occurs to me I have no idea if it will fit into my case.......... Does anyone happen to know?

My gigabyte black 1080ti has maybe 10mm spare space at the end.

Thanks

Edit

Ok so it turns out the harddrive cage in my case splits into 2 to allow large cards and will still be able to take my 2 HDDs and single SSD.
