Perfect ABS Plastic Server Enclosure from Radio Shack

[MarkHaysHarris777]

edit:  cooling addendum:  I am noticing again that an SBC with heatsink &fan, seems to be running cooler when placed in an enclosure.  The nature of the enclosure means that the fan will be evacuating the air inside the case so many (x) times per minute; rather than just moving the air over the top of the heatsink as when the heatsink &fan are in the open.  My ubuntu board(b) featured here idles in the mid 30(s)C and seldom goes as high as the mid 40(s)C; unless I deliberately load it of course. The other observation I have for you folks ( relative to the case itself ) is that the case constitutes a resonator which tends to amplify the white noise produced by the fan. So, even though the fan is now more efficient and the unit is cooler, it is also 'slightly' more noisy even though the motor is running relatively slow (but its not obnoxious ).
