It’s unfortunate you didn’t get the cables with your board, but I think they are available. I have also been looking at the Supermicro ones in case I need another.
I used both the OCULink to 4x SATA cable and 4pin to 6x SATA power cables that came in the box for my 2x 3.5" installed for now. I won’t have space for more than 4 of those in this case since I also recently installed an ASUS Hyper M.2 and it’s quite long. I can probably fit a few 2.5" on the outside of the drive trays though…
Things are starting to get tight, so I had to flip my PSU upside down because the 24pin connector was too difficult to bend out of the way of the Hyper card. I will get a shorty cable with a shorter sleeved extension at some point, but they’re all sold out right now. x16 to 4x4x4x4 bifurcation works great, and I think it’s cool that the OCULink is configurable either as PCIe or SATA. This is a sweet little motherboard.
Attaching a few pictures if anyone is interested to see how I’ve jammed it all in there. Yes, I know I’ve mounted the L9i with the heatsink the wrong direction and my cables are a mess, but it’s working for now.
