The prompt
Fix the current model and keep the overall dimensions exactly: Length = 220 mm Width = 120 mm Height = 140 mm Wall thickness = 5 mm. Keep the GPU mounted vertically. Add mounting provisions for four 120 mm cooling fans: - Two intake fans positioned facing the two built-in GPU cooling fans. These external fans must blow fresh air directly toward the GPU fan side. - Two exhaust fans positioned along the two sides where the GPU heatsink expels hot air. These fans must extract hot air away from the GPU. Do not block the airflow with solid panels. Use open rectangular fan mounting frames only. Each 120 mm fan mount must have four screw holes with 105 mm center-to-center spacing. Do not add fan models, only create the mounting frames and screw holes. Keep enough internal clearance for the GPU and do not change the 220 x 120 x 140 mm overall dimensions.
