Dell R820, need longer SAS cables (do they exist?)

[Mithril]

I could just be tired, but I've tried searching without much luck.

I've got some Dell R820 at work, and I need to know if it is even *possible* to move the storage controller to one of the middle half height slots (or one of the slots on the right rather than the left). The SAS cables are essentially exactly as long as they need to be and seem to only be viable to route along the left side. These servers have the full 4 CPU sockets.

So are there dell official cables, or failing that after market cables, that would work here? I'm concerned about dell shenanigans with pinout etc.

I'm still kinda learning here, but as far as I know Dell is using standard SFF-8087 SAS cables. Should just be a matter of finding a cable with the length you need, and the ends at the correct angle to fit your build. I need to finish watching this video, but it may be handy for you also.
