OK I get the trend of your ideas.
I do have some concerns, though:
1) your motherboard and CPU choice are incompatible in that you have chosen a AMD CPU for a Intel CPU socketed motherboard - the LGA (Landing Grid Array) of any AMD processor is not compatible with the LGA of the Intel processor socket on the board. You will need to look at one of the Intel processors with the 1155 LGA to use this board, or you will need to choose a board that has a compatible socket for a AMD processor.
Another point: The chipset on the board is an earlier "75 series" chipset. I would suggest you rather look at the newer 77 Series chipset boards.
Incidentally, should you stay with this board, do not choose any of the 4th Generation Intel processors, as they need a 1150 LGA socket (Haswell architecture [i3, i5,17 4xxx]), rather than the LGA 1155 socket of the 2nd or 3rd Generation Intel CPU's (Sandy-/Ivy-Bridge architecture [i3,i5,i7 2xxx/3xxx]) - LGA 1155 is the socket on your chosen board.
2) the HDD that you have chosen is fair, but I would suggest that you rather invest in a HDD that has a 6Gb/s transfer rate, it will be more efficient for your purposes.
3) I do not understand your need for the Netgear LAN adapter, as the motherboard is already capable of the speed available on the adapter (10/100/1000 Mb/s).
4) I note that you wish to use 8Gb of RAM. Please be aware that you will need to use a 64-bit operating system to take full advantage of this, as a 32-bit OS will only recognise a MAXIMUM of 4Gb, and will use part of this 4GB for its own needs, which in turn reduces the amount of RAM available to the system (probably in the region of 3.2Gb will actually be usable).
Other than these concerns, I feel that you have chosen well!
