EPSON MR4400E unit only. I used it for work, but I no longer need it. It has a CPU and 4GB of memory. The HDD has been removed due to personal information. I have confirmed normal boot, DVD reading, wired LAN, and USB ports. There is overall dirt. Since it is a used item, there may be other problems. It is treated as a junk item. Please use it for parts or research. Color: Black CPU Type: Core i7 Number of Cores: 4 cores Memory Capacity: 4GB to less than 8GB
