Up for your consideration are two special HP computers. There are no expansion slots and no onboard power supply. These would make a great totally silent PC if a solid state drive (SSD) were used. Alternately, remove the micro motherboard from the case and build your own home control system, test station, etc. Power supply voltage is 19.5 VDC and is included. Call for more information or to come by and see. Sorry, no texting. show contact info
