My PC from 2012 died. Not a gamer, just need a basic PC. I do lament the passing of Windows 7. This is a good replacement for an i5 class machine but, my, the technology has changed (and choices have narrowed) in the desktop world!Machine arrives with Windows 10 (home) loaded on SSD drive. No CD for reload, no sticker on unit for MS serial #. You just have to trust them. Yes, you must have Internet available to 'install' the operating system as it downloads a couple of gig.Boots fast from SSD. Will start to login screen faster than old PC revived from sleep mode. Not much shovelware to uninstall.There is support for mounting a second hard drive; screws and SATA cable included.Motherboard has additional SATA port for a third drive but you'll have to zip tie it to frame and reuse SATA cable from old machine. Perhaps a 2.5" drive could be screwed down but that's not what I had.SSD, CD drive, and big enough power supply to support 2 extra drives is what sold me on this ACER (and $$$). Both ethernet & wi-fi capable. Not sure what Bluetooth buys me on desktop but it works. The tower case has shrunk 25% since old desktop. Only fan is on the CPU. I was able to mount rear facing fan from old tower and plug it into motherboard. The old fan is the only noise this thing makes. Intel graphics drives my 32" monitor to 1920 by 1080 just fine. No longer a keyboard plug on rear panel. Your old favorite keyboard had better be USB. Your old speaker system has the right plug to reuse.Running Windows 10 on your home network to transfer files around is.... terrible. Back to SD card transfers. Argh.
