Equip exhibition centre with computers, block finally to be carpeted (3,2,2,3,4)
I believe the answer is:
get it in the neck
'to be carpeted' is the definition.
(both can mean to receive criticism)
'equip exhibition centre with computers block finally' is the wordplay.
I cannot quite understand how this works, but
'computers' could be 'it' (information technology) and 'it' is found in the answer.
'exhibition centre' could be 'nec' (National Exhibition Centre) and 'nec' is found within the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for get it in the neck that I've seen before include "Receive huge stick" , "suffer severely" , "reprimanded" , "Stop a rocket" , "Receiving a tracheotomy" .)
