CPU - A great CPU! But if you don't want to overclock, then you don't have to get the 3570k, the 3570 will be fine. If you do want to overclock then buy a decent CPU heatsink (there are tons of recommendations for those, generally the CoolerMaster Hyper series is most often recommended).
RAM - go with some 1.5v DDR3-1600. Ivy will appreciate the faster RAM. And really, do you need 16gb? If its just gaming/general use get a single 2x4gb kit for a total of 8gbs, you can always add another kit later if you somehow need it.
SSD - See if you can squeeze out something 120gb or higher - again, not sure about your needs but the 60gbs fills up quick and you'll kick yourself for not getting double for not much more money.
PSU - I haven't heard of that PSU before, and I don't see an 80+ certification on it. So personally, I wouldn't touch it, but haven't researched it personally. I usually build with Antec or Seasonic. If it indeed provides a clean 500w then it would be adequate but just go with a trusted name like Seasonic, Antec, Corsair. There are plenty of recommendations around here.
HDD: I would suggest two identical 7200rpm drives of some capacity for a RAID-1 (mirror) setup to at least help a bit in protecting your data. Again, I don't know what the system usage might be.
Case is fine and styling is personal preference.
GPU is fine depending on your needs (e.g. gaming heavily? Screen resolution? etc.)
I already got the PSU and the GPU already from the 1st upgrade couple months back. So I would like to keep those. Im mostly using this PC for gaming and my screen resolution is 1920x1080.And sorry for posting this out of template. Thank you
RAM: Great, I'm not comparing prices or anything, but that'll work nicely - But if you mount an aftermarket CPU cooler you might want to get ram with low-profile heatspreaders to avoid a problem fitting it in there. The big heatspreaders aren't really necessary in normal builds or with build that have good airflow.
SSD: At that price point, yeah that's fine. Myself, I'd spend the extra $20 on the Mushkin enhanced chronos. It's bench-tests much faster but the real-world difference in performance isn't very noticeable so the Agility 3 is fine but here's the link to the mushkin: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Case: Yeah, it's a great gaming case, plenty of airflow and options for cooling.
Well, you know my opinion on the PSU. A quality 500w will be fine for that setup. But I am dubious as to whether your LEPA PSU can actually deliver its rated power and how long it will last under such conditions. If your budget allows it, buy yourself a 500w or higher (probably around 650w-750w if you plan to XFire later) PSU from one of the brands I mentioned previously. Just put that LEPA on the shelf.
