Tom Logan made a video review about the 500R.
The NH-D14 fits just fine with the 200 mm side panel fan.
Look the video reeview here.
The PH-TC14PE is a bit taller than the NH-D14 but I think it would fit just fine with the 200 mm side fan.
Matthew Lambert made a review in the Bit-Tech about the PH-TC14PE.
The test system uses the Asus P9X79 Pro and 4 x 4GB G.Skill Ripjaw inside the 500R.
Look the review here.
I'm not sure if he can help about this question but I would recommend to try.
