Hi, I currently have a basic midi case which houses my PC I am planning to upgrade. I am thinking of getting a GTX 770 to replace my HD6850. According to measurements of the GTX 770, it will not fit in my case. The card is around 30cm. Looking at other MIDI cases, most of them despite being "gaming cases" won't fit anything bigger than 25cm. Does this mean I need a full size case? Surely not.
