We have added two fans to the rear of the case as a means of offering the best cooling possible.  We were not able to install a floppy drive to the case at this time since all the ones I had left were the off-white colored ones.  As you look at the second picture you can see that there a great deal of room even after the motherboard was installed.

The the M40 Powered up you can see what the LCD display looks like along with the top DVD-ROM we have installed in the M40.  Overall I have to give this case exceptionally high marks for a number of reason.  Starting with overall appearance of the case and ease of installation.  The split design works perfectly as does exactly what it suppose to do and that is to keep the heat separated from one section to the next.

To see how well the AeroCool M40 cooled we our standard testing methodology where we run a copy of Ultra-X's Winstress off of a thumb drive and a copy of Prime off of the hard drive.  To determine the system and CPU temperature we used the temperature gauge on the M40 and Lavalys Everest.  We recorded the temperatures both at idle and load temperatures to get and idea of how well it heat from a very active processor.  Here are the results we received.

The AeroCool has only one small quirk that one must deal with building his or her system and that is the fact that you have to be careful about which power supply you have or purchase.  Other wise it will not fit correctly and then you will have issue installing your hard drives.  Other than that you have a solid case that does what is asked of it and in return gives you a very arractive case for you to admire all for less than $90.00 USD.
