), any comments/ideas/alternatives?

I always forget about that.
Removing stuff is generally easiest ... So just unplug the IDE cable from the board, run the install with the SATA devices, and if all is well...pull the IDE device power cables. Device removal is optional.
I think the only way to get the SATA optical going in it's current position is to unplug both IDE power plugs - I think I can see an extra SATA power connector on that lead. Otherwise there doesn't seem to be enough lead length between the any of the plugs, (molex/SATA), to enable both SATA devices to be powered.
But then after install it would need to be unplugged again due to the need to have the Maxtor working, so then the IDE optical would need to be powered again, (again because of insufficient lead length between plugs) - leaving that nice SATA optical sitting all by it's lonesome again.
Aarrrgghh!

Oops! ...Caught me not paying attention. I was thinking the IDE was all done (and missed the power cable issue).
Pull the IDE optical drive, and move the SATA HDD to its position. Then just bolt it to one side (they don't torque-up
that hard), and if it sags a bit it can't go far...it's already at the bottom. Put the SATA optical in the slot above it, now the cables reach ... And the IDE HDD can have the leftovers where it's at.
...Unless there is something else I'm missing.
