Just saw the thread, Y NOBODY CALL ME FOR THIS?! >.<
For the CPU I'd go for a K processor, like the Intel 2500k; it might be a bit older than the 3000 series but if you can find it used you'll be off pretty good. I run it at ~4.6-4.9GHz.
And for overclocking (if you don't want to do it yourself) I'd go for an Asus ROG Gene motherboard, cheap yet packed with features like auto-overclocking which pushes your system easily to 4.6GHz.
For the SSD I would have gone for Plextor PX-128M5S, kinda the bang-for-the-buck SSD @ 128GB.
And the HDD? A Seagate ST1000DM003 would have been a lot better, for $5 extra you'd get 1TB. Did I say that Seagate's current HDD's are the best ones around? They currently use 1TB platters which allows read/write speeds of up to 150-190MB/s (atleast in my system); still have to see something better.

You really only need 8GB of RAM gaming, everythin above that is for when you're going to do extra stuff like editing videos or stuff like that (professional stuff if you know what I mean).
For $50 extra (the cash you'd kinda be saving with buying a 2500K) you could buy a Radeon 7950.
Games are utilizing the GPU more and more and not the CPU. If you need more CPU power you can just overclock it, it's safe and easy (a lot of people spread out nonsense though).
Because of this a used 2500K would be great, I'm using one right now and my biggest bottleneck is my GTX 560 Ti (which performs pretty much like a Radeon 7850 like I've heard, sometimes better and sometimes worse; depending on the game).
Heck you could even get better performance for a lower price if you ask me.
Used RAM for instance is a great idea, companies that make RAM offer lifetime warranty now so if you get a broken pair you could just get a new pair for free.
HDD's are another story, Seagate offers 1-3 years if I'm not mistaken; Western Digital a lot longer (if you want to go for performance -> Seagate, Reliability -> WD).
I still have to see a used motherboard break too, in short most electronics don't break that easily.
If anyone needs help with stuff like this, just send me a PM and I'll help you out.
PS: I should start a custom computer company.
