More info: I wanted a quiet, but still cool, case as I really don't like to hear it. I ended up with a "Corsair Carbide Quiet 600Q". It's not small, but with the standard fans, it's extremely quiet. Only indication it is on is the small power-led on the top and the light from the mouse. Power supply: "be quiet! Dark Power Pro 11 750W", again, really quiet and stable. Memory: Kingston HyperX 32 GB DDR4-2133 Quad-kit CPU-fan: Noctua NH-D15 I ended up with an Asus mainboard and Intel CPU. -- Joost PS. Picking parts for a new PC is always tricky. I am missing a budget-limit here. Mine probably was a bit higher then the OPs, but I tend to buy them to last 7 years minimum.
