As others have said you're seriously going to struggle at this budget because Overwatch doesn't run on a free OS like Linux so you'd need to buy Windows and that's 30% of your budget gone immediately.
What country are you based in? I'll use Germany as an example:
It is difficult to build a whole system on that tight of a budget, and finding the same things in Europe might be harder. These two get you all but a monitor.

That's about as good as I can come up with really, my laptop has Haswell integrated graphics and the game is barely playable at 720P. This system wiould perform slightly better so that might just about do it at 720P minimum settings but doesn't include an OS. If you could add a $100 graphics card later you'd be looking at 40FPS+ish minimum at max settings.
