1. The chassis fan connector is a 4 pin connector near the cpu fan connector (the two actually look very same, except the color). Read the manual for more accurate position of the port
2. Get Asus Xonar DG available for 1500 (ASUS SOUND CARD XONAR DG).
3. For >3 Gb RAM, you should always install a 64 bit OS. Get WIn 7/8 bit. If you are an engineering student, you may avail a free copy of Windows os (and win os, XP, vista, 7 and even 8) from dreamSpark account. Contask your college's admin or dreamspark.
4. that will take lots of time to type

. read this section of TDF : Freeware or browse various software sites. remember, there are always free/open source alternatives available for any software, so opt for them and avoid using pirated softwares.
5. the driver in CD is always out of date. Download the latest driver from Nvidia's website.
6. For overclocking GPU, use the utility included in the graphic card cd (download the latest version of the same). read some tutorial before doing so. And that cpu (i5 3570) cannot be overclocked. What fan setup have you done so far?
For antivirus, I recommend Norton Internet Security 2013. Very good detection, very low memory and processor footprint. You may read this thread for more information: *www.thinkdigit.com/forum/software-q/138653-antivirus-guide-user-reviews.html
