ok so i want to build a new computer and i dont know what to get, im using some of my old computer parts too. they are r9 280x gpu, corsair 1000 watt psu and my 16 gb ram. I want to get a good motherboard for around 250$ and cpu around 400$, ssd 500gb for 350$ if possible, if not 400$ and a case that looks good and has great airflow but quite too. thanks
