And above you see two hard drives installed. The cables will go on the side so to allow free airflow from the intake fans while also helping to cool the 7200rpm hard drives. Four would fit there very nicely. But 2 is best since you have more free airflwow for the inside of the case. Very simple to install any hard drives, just carefully slide them in and bolt them to the case with the included screws. I usually place thin rubber washers between the harddrives and case, but that isn't necessary of course. I just like the added protection.

The top left picture shows the rear of the case and as you can see it fits two 80mm fans for outtake. Most cases I've had barely had room for one, so this is a very useful and welcome addition. On the right shows the insides and all that room. It is a full 2 1/2 inches longer than the last case I had and that allows for more space between the drives (like the Cd-Rom, CDRW) and the motherboard, and more room to conceal the cables so they aren't in the way of the ram and also for better cooling. Not to mention so it gives the insides a better look for that window.

And below you can see how the inside looks when everything is installed. I have a cd-rom on top, a temp monitor next, included face plate and then a CDRW. And of course a floppy and 2 hard drives installed in the lower right. Also notice the front four fans. The space for them was cut out, and still with safety rolled edges so the fans easily slide behind. Notice particularly the room between the cdrom drives and the motherboard. You have plenty of room to mess around and arrange the cables about any way you prefer and no troubles changing drives.

*Note: The power supply you see below does not come with this case. After testing everything with the power supply that comes with the Blue Meany, I replaced it with another to see if there were any temp differences. There wasn't. That tells me the two fans I placed as the rear outtake are doing their job.
