OK I have discovered that two computers in the department are without case fans (unfortunately I have found out only after the HDs died, mainly because I am not in charge of these)

I have been sent on a mission to locate/price compare some case fans so we can get them ordered ASAP.

All I have been able to find are those glow-in-the-dark "computer-ricer" fans cry:
I don't think the department head will think to highly of ricing out his server.
HELLLLPPPPP!
