You can start
here. Disregard the pricing/availability of specific models mentioned in the video - this guy is speaking about a US market which is light years away from ours.
Focus on the principles being discussed here, instead.
I am sure there are other similar build how-tos that you can look at.
one other resource you can look at is pcpartpicker.com - the one place it scores over pcpricetracker.in is that each selection you make for a component, will restrict the next component that you select to just compatible ones.
So you will never ever make the mistake of choosing an i5-2400 and trying to pair with with AMD B450 motherboard.
Or choosing an itx case and a full sized ATX motherboard.
The place where pcpricetracker scores over pcpartpicker is that it is tuned for an Indian market - so this where you will eventually go to draft your PC build.
You get the gist. I would urge you to get into what is effectively a rabbit hole and ask questions about what you do not understand - keep your end goal of actually building a PC aside for a bit. Focus instead on learning what the parts do and how they work with each other. Every part choice has trade-offs - learn what they are and how you would be affected if you made that specific choice.
Read up on the step up to the Modest builds also - it might give you an idea of what the additional money spent translates to in terms of gaming/productivity value.
The Budget build - was the inspiration for my 1st build (and a similar one was my initial recommendation - message #2 on this thread)
Good luck and, importantly, have a lot of fun learning!
