Unless your going to do alot of overeclocking I would get air cooled.
128 GB I don't think will be enough storage alone. I would go with the HD. A SSD can always be added later.
560 and 7850 are about equal. 560 ti is a bit better then a 7850, or was last I researched last winter.
3570k will be faster then the 6100.
I would talk to tilldeath and compare with cyberpower. Compare warranty, repair, check about written warranty etc. ( I am just throwing this in here)
Last but not least, If you are mechanically inclined at all and have some patience. Buy the parts and build it yourself. A computer is not hard to assemble.
Downside of building yourself, no written warranty other then for parts. It breaks you troubleshoot and fix.
Goodluck
