My recommendations are at the bottom.
The CPU is Entry level. The 3.7 GHz isn't true numbers.
The motherboard is too old to upgrade the processor.
If its dual channel then u want 4GB x2.
I'd get a SSD 256 GB the price is going up or a 512 GB
Graphics cards are expensive and it's in the price range of affordable.
If you like the case then that's what matters.
The power supply if you get the white version I think it would be outstanding.
Go for windows Ultimate 10 it does stuff like a version of VM ware and updates can be downloaded automaticly and doesn't restart in the middle of the night if you have applications open.
Most routers can't use ac speeds without costing lots also you get higher pings sometimes and you get ringing (measurable) in the connection. Prefered method is Eithernet.
After you put the equipment together the monitor is where you will spend your life staring at it. Black is a good choice for beisel. But before you buy I would see it in person.
My recommendation:
I would wait for AMDs Ryzen CPUs and motherboards/chipsets.
I have studied every piece of literature confirmed and speculated and watched the AMD streamcast video.
I saw samples did not have boost turned on (your terminology might be Turbo boost).
The number of cores were 8 cores 16 threads.
In blender Ryzen i7 8/16 cores/threads with no boost was 5 seconds faster. I can't remember the times but that was at least 5% faster.
The temperature of operation was lower than Intel in wattage, though max temp was not disclosed thermally.
The rumor mill which could be wrong was $400 less than Intel's version of $1,000.
First to be sold is this model and from the horses mouth (AMD CEO) There will be a large stockpile for release.
Then their going to be making CPUs with less cores and I suppose different speeds.
Similar their going to make server chips 32/64 cores/threads and 48/96 cores/threads.
My guess and I'm just guessing is that similar Intel i5 4 core will sell about around $100. The CPU your specing is $70
I would buy a AMD i5 and the cheapest motherboard, add 4 gigs of ram and another 4 later and the rest of the costs are going to be about the same except SSDs will go up due to demand of memory and a better video card will come in the same price range. In the future additions will be hard drive and you will have an upgrade path in GPU not limited by CPU and possibly some games will want more memory. Possibly the AMD i5 will have 4/8 cores/threads. The road map indicates there will be Ryzen, different letters before but includes i3 distinguishment.
When the i5 will arrive nobody has speculation but could be later to push sales of higher tier products.
Present i7 product 2 months and before 3 months time frame. (March)
The clock verses execution is a 40% gain using machine learning and something else.
