Just a report/small information.
Some time ago I got a riser for my M720Q from
@WifiCable and recently received a "Fujitsu" LSI3008 card from Aliexpress and finally got some time to mount it and test it out.
So far it works as expected and although a thigh fit the card and the m.2 slot can be both used at the same time, and the WiFi m.2 slot is still accessible (I had a WiFi card in there for some time).
I have made a janky NAS using a Ubiquiti UNVR chassis with a couple holes cut out so I could run the SAS cables, and a big hole so that an ATX PSU fan can pull air, to cool the HDDs as well, so I'm running my M720Q without the top cover, and it wouldn't fit anyway with this HBA card..

I had to remove the RF gasket that was on top of the audio jacks, and added a bit of electrical tape just to play it safe.

I suspect that the metal bracket is kinda crooked and doesn't allow the card to sit properly on the chassis, I need to make a small L bracket to screw the card into the chassis, for now its propped with the RF gasket removed from the audio jacks wrapped in tape so I dont short this mess.

And a side view showing the free space between the extra m.2 slot from the riser and the PCIE card, it has around 2mm, and for now that SSD just runs at 38-39ºC, its fine!
Oh, and I didn't take a photo, but soon after getting storcli working I found that my HBA was running at a toasty 86ºC, so I grabbed one of the 40x40mm fans from the UNVR chassis, powered it with 5V and secured it with a ziptie to the HBA heatsink, now it sits at 51ºC.
For now this thing is my home server, running OMV with a pair of Toshiba N300 8TB HDDs in RAID1, plus a USB 6TB HDD (soon to be chucked now that I have the HBA), plus another USB 2TB HDD, and two 512GB nvme Samsung SSDs, running jellyfin, qbittorrent, Home Assistant VM on KVM and being a file server.
