Am going to try to build my own. Have been picking up components here and there for about a month, some were given to me. But can't decide on final pieces. PSU and Graphics Card. Computer will be used for basic office duty in day and light to medium gaming in evening. Micro Center (pickup), Newegg, TigerDirect are all ok.
Here is what I have so far:
CPU: Intel Core i5-3570K 3.4GHz Quad-Core Processor
CPU Cooler: Coolmaster Hyper 212 EVO
Motherboard: Asus P8Z77-V LK ATX LGA1155 Motherboard
Memory: G. Skill 8GB (2x4GB) Ripjaws X Series DDR3 1600MHX (F3-12800CL8D-8GBXM)
Storage: ** not sure yet (considering a SSD and a hard drive combo)
Video Card: ** less than $150.00
Sound Card: NOT NEEDED
Case: CM Storm Scout
Power Supply: ** less than $100.00, would prefer Modular.
Monitor: NOT NEEDED
Operating System: Microsoft Windows 7 Home Premium SP1 (64-bit)
Keyboard: NOT NEEDED
Mouse: NOT NEEDED
Obviously get the 3570k with motherboard bundle from microcenter. Same price as the CPU Itdanzu posted and you can get a deal on Z77 board.
PSU loads of options, look for either corsair, seasonic or antec (I like them) loads under $100 and newegg has several deals on them right now. Antec BP550(use this myself) for example on sale right now $50 or corsair CX600 http://www.newegg.com/Product/Product.aspx?Item=N82E168... for $50 after rebate (obvious choice duh).
Storage depends, how much do you need what's your budget? Two common possibilities
Either get a 128gb SSD ($60 on sale they come and go, got a vertex4 for $55 the other day, also had corsair4 and others on sale) + regular HDD (2tb seagate 7200rpm $99 http://www.microcenter.com/product/383892/Barracuda_2TB...) for storage
Reason I suggested that cpu is because if you aren't ocing there will be no noticable difference, and with that money save he could get more gpu power. But if the microcenter is a really good deal, I would go with that. The 7850 is decently stronger than the 560 for only a few more dollars, I still can't find a 560 for under 170 though. Also the problem with that after rebate price is that rebates often times don't work and I would never rely on a rebate, just look at some of the reviews.
