Expensive PC but i sat on a foldout chair, foldout table, 1080p TV i got my for 16th birthday, membrane keyboard and madcatz mouse. It was a while before i got a proper desk and chair even longer before i got a decent monitor. Didn't even have a headset or mic would use my phone and turn the game volume down
