I'd join my voice to bigmicke7 and strongly advise a test with different PSU to avoid possible complications.
No display means If my memory is correct either Memory problem or GPU issue (graphic card = if integrated then it's the whole mobo), but taking in consideration the blu-ray drive not powering on, it's more methodical to eliminate the PSU from the equation to get to the bottom if the issue.
some molex are cheaply made and the metalic pins slip out (need special attention when disconnecting or connecting them) and touch each other (experiencing this issue first hand with some cheap ebay molex to X4 3pin fan splitter connector) and need to be secured nicely with tape.
you could also anticipate testing with a different set of ram, or with ram at different ram slot etc ...
I would also RE-test the SSD drive in different conditions or in a different tower.
