Thanx for all comments it realy motivates me, I just want to go down in the garage and continue the case but I don't have any mdf board left . I will go to the town on wednesday and buy more mdf for the back, the top, and the right side, so next update will be on wednessday . @ exitus : that's a great idea, I will do that! @ Dira and elbarto241 : I don't think I will use dust filter because I have ceramic tile in my room and don't have so much dust in my current rig (has been running for over a year whitout filters). cya !!
