Rob attached is a picture of the case with the lucent in it. Just to make  
sure it fits. I use these cases extensively and have gotten some in the past 
for  my Swiss friend. I have two tbolts in them and in one case have fan 
control. Use  an analog temp. control with 12 V fan. Where and how you place 
the fan depends  on what you need on the back plate also concern for noise 
and vibration. If you  want more please off list.
Hope the 88K file makes it.

Hi  Bert,

I could not find your earlier post about this, can you give an  example? 
What I could find is your remark about forced cooling. How about that  with 
the eighties HP case?

Best  regards,
