A Closer Look – 915F Interior
On the interior we see the real differences to this case when compared to the 915R. The motherboard still goes at the back, and there is still a 5.25″ drive bay at the front, but you also get a vertical hard drive bracket at the back, which can be used to mount drives using screws and rubber washers. The PSU is mounted up at the front, and this gives you flexibility in terms of component layout as you can take advantage of the later rubber grommet cut-out at the back, perfect for passing through water cooling pipes to any side mounted radiators.
The hard drive bracket is completely optional and can be removed with four simple screws. Actually, just about everything is option in the HAF cases, the hard drive bays and the optical bays in all three cases can be completely remove and interchanged as you see fit.
