Case Fan and PSU Fan:

As we plan to turn this into Media Center noise in particular fan noise will be an issue. So for now we have replaced the case Fan with an Akasa version and this also has the benefit of a standard motherboard connection so we ditched our modified setup and plugged the case fan straight onto the motherboard. With the case Fan noise dramatically reduced it was clear that the PSU Fan needed some attention so we dismantled the PSU and removed the stock Fan and replaced it with the Akasa equivalent with in this case a small switch to control the speed. This switch exits nicely through the blanked of hole in the PSU which must on some models contain an on/off switch.

3.5″ drive space:

The drive caddy has space for an external 3.5″ drive which we used to add a card reader and front USB and Audio outputs. You could also use it for a floppy and combined card reader. You do need to cut the front panel for this unless you are lucky en ought to get a case with the optional Zip drive fitted. Our panel was cut to size very carefully – to prevent the plastic splitting we covered it with masking tape first and drew the outline of the cutout on this. The best tool for this job turned out to be hand jigsaw the dremel tended to melt the plastic when a test cut was made. Oh the Apple logo is illuminated we drilled a hole in the case to allow the blue illumination inside the case to come through.

Graphics Card: MSI GeForce 7600GS 512MB AGP

We chose this card for many reasons one for the heat pipe technology so there’s no Fan and two it claims to have HDTV output which may come in handy if we decide to upgrade the optical drive for a HD drive eg. Blu-ray etc. We’ve not tried this card before so it’s a bit of an unknown quantity but we have high hopes.

Case illumination:
We’ve added two blue light mini fluorescent’s for case lighting. One we’ve glued under the case the others mounted internally at the top of the case. We love the effect of the blue light coming through the case and being picked up by the external plastics, especially around the door release, Apple logo and the case handles.
