Hello Mengu, 

I am making feasibility study of migrating libraries of Masaryk university 
in Czech republic from Aleph to Koha, and I would like to ask you, what 
kind of hardware do you use, some parameters would be great to know.

Is it possible for you to provide these details?

Thanks in advance, looking forward for your reply.
