The maximum size of a card that fits in the G-Series is 206 mm (L) × 98 mm (H) × 16 mm (D). But due to the different layout designs of each model and VGA card, we strongly suggest to check our VGA support list for each model or test before purchasing the VGA card.
This is because the Intel VGA driver version (6.14.10.4543) is conflicting with the ATI A9250 PCI VGA card. In case you want to run this card, we recommend you to use the driver version (6.14.10.4421) from here.
