I would agree with the above as well. Stay way from El Diablo and get a better brand PSU. Also, the Phenom II's were good in their day and still are if you already have one. I wouldn't buy into them though. If this is a general purpose PC I'd look at the APU's as they would give somewhat similar CPU performance, but have a decent GPU build in for any graphical stuff, which even your OS and browse are needing now a days. See below for my recommendation. I think it works out to be only a few bucks more, but you are getting a fairly decent system for general use. I'm assuming you have all the other pieces parts like case, optical drive, OS.. GFs coworks? Hope your getting something out of the deal.
CPU: AMD A8-5600K Trinity 3.6GHz (3.9GHz Turbo) Socket FM2 100W Quad-Core Desktop APU ($100 after $10 promo code)

Great general use CPU and for $100 it's a good deal as it is couples with pretty much the best onboard graphics out there.
motherboard: ASRock FM2A75M-DGS FM2 AMD A75 (Hudson D3) SATA 6Gb/s USB 3.0 ($54.99 + $5.99 shipping)

Has SATA3 and USB3 so it should be good for a while
RAM: Kingston HyperX Blu Red Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 ($36.99)

Since the motherboard only has 2 ram slots I'd just pay the extra few bucks for 8GB of RAM
HDD: Seagate Barracuda ST500DM002 500GB 7200 RPM 16MB Cache SATA 6.0Gb/s ($59.99)

500GB SATA3 drive should do the trick. This was $20 instant savings and should perform fairly well and give a good amount of storage.
PSU: CORSAIR Builder Series CX430 430W ($39.99 + $20MIR)

Just a really good deal on a decent PSU. It has some room for play as well if other components are needed. Honestly, with this system you could get away with a 350W.
