A:Answer Yes, it has a tooless opening case, it's super easy to get into. The hard drives can be changed out for more TB's if so desired. The video card does not have an SLI connector, however you could switch the 1060 card out for a 1070 or 1080, you would probably want to switch to a higher wattage power supply too. It has onboard audio, but you could add a Soundblaster card if so desired. You can increase the RAM to 64GB versus the 16 that it comes with, you could even switch to the i7, 4.0, 6th gen processor, but that would be a waste of money. You can add liquid cooling or more fans, the case is large and will easily accept modifications. One thing to remember is tbe case does NOT have any front accessable bays, as it's solid steel, so any type of a cd/dvr or blue ray player will need to be an external unit, connecting through a usb port.
