(by someone who doesn't know how)
So that day we saw a estate sale, and there was a Gateway with a monitor, and a solid flight simulator setup.
I paid $20 for a pentium beige box, a VGA CRT monitor, and a mouse. (and cables)
Ok after buying a keyboard, I tried to boot stuff, anything really. but it seems that windows 95 has been deleted, kinda part of it is there but it won't work still. so i open it up, a section of the motherboard is on the bottom. So I need to buy a new motherboard.
