The PC itself is good quality with plenty of remaining life. It is a bit slow for two primary reasons: 1) it only has 8 gigabytes of RAM and 2) it does not have a Solid State Drive.Trying to run Windows 10+ for everyday tasks takes longer than usual because there is significant read-write activity happening on the Hard Disk Drive. This is an extra PC for our craft area so high performance is not critical.The refurbished job was adequate as expected and the keyboard and mouse are the lowest quality possible. Wireless connectivity is achieved through a wifi USB dongle which works fine. We have ours hard wired so do not use WiFi.With full size  SATA HDD there is one space for small HDD or SSD and the supplied SATA cable has one power plug available but you will need a SATA data cable to add a drive, or use the one from the DVD drive if you do not plan to use it. (We are not likely to use our DVD drive)The PC cam with two 4GB DDR3 DIMMs for a total of 8GB of RAM. There are a total of four RAM slots with the supplied RAM occupying two of the slots.I will likely keep the PC, but add an SSD for the Operating System, and 8 more GB of RAM.Overall okay PC out of the box if you are willing to accept the moderate speed.Hope this helps.
