I've been building my own PC's for over 20 years...and built my latest one just recently.
But like others have said, we need to know what you're using it for before offering recommendations.
For example, if you're going to be doing video editing and/or intense gaming, then putting an Intel i5 & middling graphics card in it would be bad advice.
But if you're using it to surf the web, email, watch porn, normal office/personal work, etc, then those parts would be great economical & strong choices. Most people don't know that even low-to-mid-performance parts are more powerful than their needs, so they waste a lot of money on high-performance parts and never use 1/10th of their potential.
And don't go cheap on the case.
Proper presentation of your build is a statement.
