From a quick glance, I can tell you should get a monitor that has better than a 5ms reponse time for gaming you may end up with ghosting problems if I remember correctly. Something in the 2-3ms response range would be better. And for a monitor you can pick up ones that draw half the power easily for around the same price and probably even better spec. It may not seem that much but shaving 25w over course of how long you may end up using said monitor can help pay for itself, with no downsides if you do a bit of research on what to get.
I can't make any recommendations though as monitors are not my specialty, but hope that helps. Beyond that in terms of build, the tower looks solid without anything needing to be changed from a quick glance.
What is your OS. If it is Win. 7 64 bit , and you are going to have it on the 64gb SSD , then I would consider a little bit bigger SSD because it will fill up awfuly fast. I had an Intel 64gb for my first SSD and loaded XP 64bit and before long I was at 55gb , so I got another and put my games and other things on it. If you can catch a good sale somewhere a 240gb seems to be the sweet spot for SSD's. But that's just my take and anything between 120gb and 240gb would be fine. I know that ram prices are extremely low right now and I always say the more the better but if you do neew to make a cut somewhere then 8gb of ram is more than enough and if you don't need to make a cut then keep the 16gb (more is better).
