Questions about Sharkoon QB One

In principle, YES. The old 3.5' HDD - if equipped with SATA connectors - are plugged directly into the mainboard. If they were external USB HDDs, you could plug them in from the outside ... As you can see, there is no simple answer to this question ... It always depends on the actual components, which should be compatible with each other. Computer development is constantly progressing ... and new standards see the light of day ... so my statement should be taken with a grain of salt ... but there is room for 2 HDDs :-)

It is very tight - depending on the tolerance, it can be "too tight" and the lid must be pressed on a little. If possible, I would recommend a slightly smaller cooler (e.g. a Cryorig M9) and an additional fan in the back.

The height is not the decisive problem. Because of the height, you only have to loosen the cable ties holding the power cable and guide the cable around the graphics card a little. But it is much more difficult to get the graphics card into this position at all. It doesn't look like it, but from every angle there is something in the way that prevents you from positioning the card. I got this exact graphics card in by removing the hard drive cage (metal part above the power supply). I simply drilled out the individual rivets. The integrity of the case was not noticeably affected. But the hard drive cage is missing.

Only the case. Without other PC hardware.
