Your bays are full, but are you using all the sata ports on your board? 
You can get simple brackets that let you mount a normal sata drive in a 
pci slot (no connection to the actual slot connector). If your slots are 
all spoken for, you could combine a bracket with a generic sata card in 
another slot (assuming you have multiple slots free).
