Do you know of any concerns of using all the ports on a motherboard?
Slowdowns or anything like that?

I've one box here that's using all six onboard ports on an Nvidia MCP55 
controller.

Two ports are a RAID 1 for the OS and the other 4 have 4 x 500GB drives 
as a RAID 5.

It flies along at the speed I would expect - the array started out as a 
3 drive RAID5 and after I'd grown it to 4, I tested it with the 
filesystem 60% full and got 160MB/s writes and 178MB/s reads.
