A couple month ago I got a computer for like £100 or something. It was decent, had a okay cpu, okay motherboard, needed a new power supply but I was intending on just upgrading it. The only thing it really needed was some better fans, a gpu and a better power supply. Although (this is my first time upgrading by the way) I realised I had no screws to support the gpu I heard somewhere that it's supposed to come with the case so I'm wondering if I just need a new case or do the screws come with the graphics card? Thanks.
