Корпус mini ITX + блок питания + материнская плата + процессор + жесткий диск 500 ГБ

Mini ITX case with Power Supply 

DVD rom

Intel D2700 Mainboard. Atom D2700 CPU on board. 

500GB HDD. (not working properly)

No ram included. (it uses ddr3 laptop ram) 

I don't think that you wish to use atom but if you do, most probably you need another hard drive. Selling as is.
