Iv just Recieved this case to go with the rest of my new build. The last time I built a PC was 5-8years ago so it might just be me missing the obvious. Iv come to the point were I'm abouts to mount my 2.5 HDD. The case states (also checked in manual) 4 x tool free 2.5" SSD hard drive but I can't figure out how it fits. The bay is too wide, is it suppose to just sit loosely?
