A YouTuber from my country (Serbia) made a video for a budget PC build (250euros) more or less depends on prices changing

Not included : computer case/keyboard/mouse/monitor as he already had those

I found almost all the stuff needed from the build cost about 200euros with the computer case (different mother board it's called AM4 B350 or something)

I own a mouse because i have an old laptop (slow and lags don't use) Missing : keyboard and monitor

Thought i could use my TV instead of buying a computer monitor now (no $$$)

Can buy a cheap keyboard for like 10euros

That would complete the build i guess unless I can't use TV...

So basically will this work? Also what to do next i need to buy windows i guess (maybe there is something to do before?)

Any other stuff needed to be done before/after is where i am lost (watched YouTube videos but im just confused now)

This will be my first PC build hopefully(also first PC..own a laptop)

I wanted to try this build for the games he showcases playing in the video (League of Legends and Apex also played those before)
