I have successfully installed the 12.5 mm WD Scorpio Blue (1TB) in the upper bay. I do not have a heat issue, especially after replacing the heat sink interface with Arctic Silver 5 Thermal paste. Its snug, but it slipped in easily. I agree with ABCellars with regards to the SSD as the boot drive. The WD is only 5200 rpms but it is plenty fast for a storage drive. Power consumption is well within the capabilities of the power supply, so I wouldn't worry about that.
