I'm loathe to recommend a 92mm tower for an 8 core fx BUT this will absutely do the job.

If you're careful you can get away without removing the motherboard from the case (the cooler uses the stock amd backplate but you do need to unscrew the stock amd cooler mount from the front of the board)
Its expensive but good.
Other options
Cryorig h5(none in stock anywhere I can find at the minute)
Raijintek Pallas - big 140mm blower style cooler

Both the above would necessitate motherboard removal as it looks like your case has no rear CPU tray cutout.
