Beg pardon for my misunderstanding and for attributing you an undue comment.

Though the start was not fast. The Debian amd64 net installer (although a UPS
was upstream and the new fan - see belo - installed) did not like one of
them, indicating to return it to the vendor with CPU0 machine check exception
4 Bank 4 TSC ..., through decoding mcelog --aschii. The vendor wanted to
check the disk (June 2006 production) on his preferred OS, whereby no
indication came out, but the machine did not put the disk to work. I am
waiting for the replament Raptor.

That I have done, placing the large fan in on the fron side of the Enermack
case, directly onto the drives.
