First time build!

[dejesuscreations]

After searching tones of sites and getting advice from anyone and everyone this is what i ended up with. i have never built a computer and knew basically nothing about ram, ssd, pcu, AMD, PCI. like i said i searched and searched learned what i could and tried to make the best sense of it. Any suggestions i would be using this system for auto cad, adobe illustrator , gaming, cd writing, videos..not all at the same time of course.. just looking to see if im in the right direction any feed back is great for my learning experience
