ok so in short my buddy and i are trying to start a youtube channel andwe live multiple states away from each other, so trying to send my videos to him for editing is a pain. how would i go about building a sever that we could transfer the videos between each other more easily as videos are recorded by me. i have some old computer parts lying around i could build something with. i just need to know how i would go about this FOR THE CHEAP!
