Here is a system that is far superior the one you had originally.
You have a quad core i7 with hyperthreading, the latest one which is unlocked and can be overclocked, an aftermarket cooler for it which is cheap but effective.
16GB of RAM that only occupies half of the RAM slots, so you could add up to another 16GB later on if you find yourself using all of the 16GB
6TB of storage for video files and a fast 256GB SSD for your OS and applications.
Case is the one I have, it's a sleek black silence optimised case without a window or anything flashy but it's lined with sound deadening material and has a nice metal door that also is lined.
You have a capable GTX 780 video card with plenty of CUDA cores to support acceleration in your Adobe apps.
Power supply unit is high quality with a 10 year warranty.

Let me know if you want to change something, it would be possible to move up to a 6 core 2011 socket platform which would improve performance, but will cost more, I don't really know much about your workflow or how much rendering time is needed to be chewed through and whether that would be a cost effective benefit.
