I dont think the MOBO has enough memory sockets
32GB max.. geez. I would build it in a heartbeat if I had extra money hanging around. (I'll have PC envy)
If you do a lot of rendering in AE and animations then go for it. If you don't do alot of that then ask yourself-- what would be a better choice for less $$. If you are like me, I build a new NLE computer every other year. So I don't stick too much $$ into it.
