Total is less, and you get an i5 2400 as well as a much better PSU. Granted you will go from H67 to H61 you won't notice the difference. As for DDR3 1600, it doesn't work with H67/H61. Both don't support the speed.
Yes I did look at your advice and changed the CPU from the i3 to the i5. I'm not sure if I trust the asrock motherboards yet. Also something seems fishy about that company that sells windows for 70.00 seems that they might be doing something illegal.
That's fine if you don't trust the company but I'd suggest just going with the SSD for what you're doing. It'll boot fast and save you power as well as be enough for storage.
You don't need a GPU, the i5 2400's iGPU is good enough for what you want to do as Azeem stated.
Your PSU is still the same the older CM's will crap out on you. They use cheap capacitors and so that results in short life. For the price you might as well pay a little bit more and step up to the CX430V2 I suggested.
Both will be equivalent in performance since no motherboard is different by a huge margin. I would say the Asrock offers the same performance and maybe slightly better. But defiantly with the money saved it's worth it. I just posted that review and you can see that it's a good board.
