buy Co-extruded PBT

Multiplus is the largest of Indonesia business center, focusing on internet cafe. We currently have project to convert our existing 100++ stores into modern business center with a minimum of 40-60 PCs. We would like to buy PCs that save space (zero-footprint) and with the lowest possible power consumption (less than 100 watt) and capable of running 24 hours/365 days.
For a start, we will buy 100 PCs for 2 stores and if it proves successfull, we will immediately convert our other 100++ stores in 1 year. We also just won a tender to open 400 more stores nationwide in 3 years. So we really need to have a heavy duty, zero footprint, and energy saving PCs.
Please give me more detail on what is available from you. Look forward to receiving prompt response from you. thx.
