here is a description how to model it
first if you could draw a blueprint is better if not use some images to see how should model it
start out with a Box for the console , but the lid will be seprate

connect the edges and move vertex es to find the shape
then for the places that i have show in picture
select the polygones then Delete them , and then select the edges and extrude them in mines ( - ) and then after you did that select the edges that you have made between the old edge and one which has been extruded , and connect them with the number of 3 or 2

start modeling and send some picture so i can tell you what you are doing wrong
dont forget to send WIRE !!
