Would a 12 inch card (Sapphire 280x) fit in a mid ATX? All the parts are online so no way to actually know without ordering
How much are custom psu cords usually? Anyone have a good maker to recommend?
You can usually see how large of a graphics card the case can hold on Newegg. For example, this Fractal R4 can support 290mm graphics cards with the HDD cage installed and 470mm cards with the HDD cage removed. Other cases should have this information too. If you can't find it, then try Googling the case you want and visit the manufacturer's website, they might have more detailed specifications there.
