I have my first rack now. It is case for 10 U on wheels and is totally covered but not fully weather proof. It is lockable to a limted extent. I now need a good power bar for this rack. A dual pentium III server for this rack would cost about 400$ US or about 500$ CND. A cheap laptop might be a better idea. I am thinking of writing a book about open source music workstations. I know nothing about Linux music workstations so would present it after and as I learned these workstations.
