Hello I was wondering what kind of components I could fit in my Hp p2-1317. the case is 35.5 cm (14 inches) Tall. 16.5 cm (6.5 inches) Width. 38.1 cm (15 inches) Depth. I will use for gaming but nothing overkill I just want to spend about 300 dollars. I have a power supply with it and a 1 teribite hard drive.
