Does the motherboard not have integrated graphics, also I'm not much of a gamer and am happy with the 3770K.
The mobo has the connections for integrated graphics, yes, but the iGPU is on the CPU itself. If you're not gaming, then that will be sufficient. If you do want to game a bit, it'll barely be passable with lowered detail settings. Nothing at all what anyone would consider great though.
You don't need a 650W PSU without a dedicated GPU, though. A good 450-500W unit would do just fine. The only reason that I would recommend going with the PSU you selected is if you think you might want to add a dedicated GPU later.
Looks good to me! I couldn't find the specific model of RAM you mentioned, but pay attention to the timings of the RAM, not only the clock speed! Check out http://en.wikipedia.org/wiki/CAS_latency for a fair comparison for RAM with different clock speeds and timings.
Also you might consider getting a smaller SSD (128GB) for the OS and getting a big hard drive for data storage. Maybe even getting 2 hard drives for a RAID1 setup for redundancy.
+1 for a smaller PSU if you are positive on never getting a GPU.
Pretty good. 64 GB is fine for the OS if you will not install many applications. My desktop is my gaming and work PC so 128 GB is barley enough. The hibernate and Paging file will take up 16GB alone (your RAM size). You can always lower those values (I always do). The OS will take 20 GB or so. If you plan on running a virtual OS or another partition 64 GB will not be enough.
Just take note of what you plan on installing and do the math. You can always install to the Data HD, but then you are going to get slow loading times. I am unfamiliar with the HD, but speed on the data HD isn't a priority (depending on what you are doing of course). Personally, I don't need a fast HD so I choose the green HDs. The green HDs suck for the OS but are fine for data.
