I have thought up a gaming PC build which will cost me over $800. I tried out a PC building website called "PC Part Picker" which is a PC building list and guide on what to buy and compare. For my lightweight gaming PC I call it, it will have an Intel i5-7500 processor with an Nvidia GTX 1050 Ti 4GB by MSI. Since it'll cost me quite a bit of money, I'll start saving up to get the parts for it and get it built soon. You will also notice that there's no storage that I've picked on my list because I have a working 500GB HDD from my PS4 when I first bought it.
