Please use pcpartpicker and it offers the cheapest to expensive in a great visually appealing and useful way. I also suggest vising the subreddit /r/buildapc AFTER you use pcpartpicker to choose your parts and get feedback on it. They are great people helped me build my first PC

PCPartPicker is a great tool to start building your PC. It also shows you others PC builds that break down the cost for you. They have a whole section of pre-built PC's and you can see them in action with real images. 

It allows you to pick CPU, CPU Cooler, Motherboard, Memory, Storage options like hard-drive/etc, the case, the video card, case fans, headphones, mouse, and even keyboards all within the site, so definitely check that out. If you are looking for a budget PC, definitely do take a peak at some of these pre-built computers. If you are new to building PC's, try asking a friend that you trust with building one for you. Be careful, because some people like to switch out parts in PC's for bad/older parts, this has happened to me and my  family before.

Good luck!
