7 + 1 expansion slots
I originally bought it because while waiting for my motherboard to be delivered I was panicked because it seemed unlikely that my Noctau CPU cooler was going to fit inside the Obsidian 250D case I had bought and immediately had NewEgg ship me my second choice case which was this Refine R4. Everything did fit into the 250D case and I decided to keep the Refine to use in the future when I needed to use a graphics card. Now, I don’t know when I will need a larger case so I am selling it, unused - I only opened it to verify that it was undamaged when it arrived.
Look about half way down the page on the following link for "Define R4 Black Pearl" and you can read the PDF product sheet and pages 3 and 4 of the manual for details of the case: http://www.fractal-design.com/home/downloads
Amazon lists Refine R4‘s as starting at $176, obviously you should buy a newer smaller Fractal-Design case before paying that. Or buy this if you want the space in a beautiful quiet case. https://www.amazon.com/Fractal-Design-Define-Cases-FD-CA-DEF-R4-BL/dp/B008HD3CTI/ref=pd_sbs_147_1
