Alright sorry for the delay. I currently don't have time but here is a post I made to another OCNer for their budget rig.
I'm sorry I won't post the links but I assure you my prices are right.
All prices are from Newegg.com
Corsair A70 $46
WDC Blue 500GB $44
MSI P67A-G43 $120
EVGA SuperClocked 560 1GB $200
G.Skill Sniper 8GB 1333Mhz $85
XFX 650w 80+ Bronze Modu $88
A-Data 500 Sata II 64GB $85
Any case up to around $110
Time to explain things
I chose the 2500k because you stated that you were looking for it. The i7-2600k is better for designing and such as it has more threads, but you might have to sacrifice the SSD for it.
Instead of the Hyper 212+ the A70 beats it by a small margin, and it includes another fan just for $5 more with a big rebate.
The WesterDigital Caviar Blue is a great all around drive. Great for storage in your case for a great price.
This motherboard is truly awesome. It has great overclocking and has many features that other boards its price don't, such as x8/x8 on dual PCI-E for later SLI or Crossfire.
The 560 is a relatively newer card. Somewhat of a budget version of the 560 Ti it is still great. It can handle pretty much all newer games, but no hardcore settings. You can bump to a 6950 1GB or a 560 Ti 1GB for an extra $50.
This is just RAM and its pretty good for its capacity. G.Skill always makes great RAM with a Lifetime warranty.
As for the PSU I have to go budget. 650w should be great for your system, and that PSU has 4 eggs out of 5. Also it uses a single 12v rail and it is MODULAR!! Awesome for cable management.
As for the SSD, it was the largest capacity for the awesome price. It boasts highspeeds up to 230 for sequencial reads but don't expect that.
It will leave plenty of space for OS and programs.
Corsair managed to get MS Office and Windows 7 to ~14 GB
Finally it comes down to the case. As for the case any will serve you well as long as it has good airflow and a good design. Two a recommend at this price point is either a Fractal Design R3, or a NZXT Hush 2.
Either are both goodlooking and have great features. You can spend less on a case to safe money.
If you catch the NZXT Phantom on sale GET IT. Truely awesome case.
That's it for now. PM for questions and comments.
For your specific build, base it off of the text above. In order to meet your requirements choosing 4GB of RAM instead of 8 will lower it. Changing you case to a $50 budget case will lower it as well. Get rid of the SSD, and lower the GPU to a 460 1GB or a 6850 if you really want to save more money. Add Windows in there for 7 and theres a good build. No monitor of course.
