Reads pretty powerful to me. All I'd add is to check that PSU capacity and availability to power the Graphics card (You'll know some have dedicated power lead needs).
As I understand it, those solid-state drives only speed up Booting, so the cost is high if the PC is rarely switched off. Did I read the OS HDD is 240G? Somewhat undersize, IMHO.
Also you said you have several extra drives "available" - worth checking these can be plugged into MBO as I had an issue with AHCI (was it?) where the MBO wouldn't accept extra drives, even though the SATA sockets were there.
Finally, have regard to noise...if you are video-editing the roomneeds to be fairly silent (so you can hear subtle audio-effects).
Even now, I wish I'd gone for a multi-core hyperthreading processor, for extra speed when rendering..
Good luck.
