Morning, SD.
Ummm... if there are no case fans fitted, how are you going to install any? Cut a hole in the case? Perhaps you mean CPU fans?
The case is physically able to accept fans ie: mounting holes are drilled as are the exhaust 'perforations' and the CPU does have a fan.
I think I'll go down the road advocated by Keef (ta) and use it as a Linux box of some description until it expires.
Thanks all!
