Re: 1st question from me (Custom Built vs Retail Built)
The only problem with building your computer is the actual BUILDING.
Especially if you don't know what you're doing; like me for example.
I ordered most of my parts and I'm gonna use a guide to build it.
If you have confidence to build it, then buy the parts you want and save some money.
If not just buy it retail; just remember you get better performance with one you build 99.9% of the time.
