I am brand new to this forum and so far I have looked around and it seems as though great advice is given out, so I figured I would try. I have built computers in the past, but not within the last six years. So if I answer some of the questions badly, please be lenient 
1) What will you be doing with this PC? Gaming? Photoshop? Web browsing? etc
Gaming, Web browsing, AutoCAD
2) What's your budget? Are tax and shipping included?
1400
3) Where do you live?
Arkansas
4) What exact parts do you need for that budget? CPU, RAM, case, etc. The word "Everything" is not a valid answer. Please list out all the parts you'll need.
MoBo, CPU, RAM, GPU, PSU, Case, Optical drive (DVD-R) (I am building from NOTHING, so everything would be a good answer minus the mouse and keyboard)
5) If reusing any parts, what parts will you be reusing? Please be especially specific about the power supply. List make and model.
None
6) Will you be overclocking?
Didn't plan on it, but minimal if any.
7) What size monitor do you have and/or plan to have?
SAMSUNG BX2031 Glossy Black 20" 5ms LED BackLight LCD Monitor Slim Design 250 cd/m2 DCR 5,000,000:1
(unless this is not a good one to buy)
8) When do you plan on building/buying the PC?
2 - 3 weeks (unless something big and new is about to be released)
9) What features do you need in a motherboard? RAID? Firewire? Crossfire or SLI support? USB 3.0? SATA 6Gb/s? eSATA? Onboard video? etc.
I am very open on this question. I also do not know what a lot of these things are
10) Do you already have a legit and reusable/transferable OS key/license? If yes, what OS? Is it 32bit or 64bit?
No
