I needed to replace an old PC, running as a server for my personal weather station, which has been running 24/7/365 since early 2005.This PC fits what I needed, and at a great price.  It even has a serial port which I need to connection to my weather station, without having to fool with a USB/serial cable.  The PC comes with Windows 10 Pro, which I also required for remote desktop connection to this PC (Home versions don't allow remote desktop connections).  A great big plus is there is NO BLOATWEAR, which can take hours to remove and cleanup.Spent a couple hours installing the latest updates from Microsoft, then installed the weather software and copying all the data from the old unit to this one, and it is running great.I'm impressed with what you get for $178 I paid.  i5 quad core processor, 500GB drive, 8GB RAM, 1Gbps Ethernet, capable of 3 monitors, a serial port, plus lots of USB2 and USB3 ports on the front and back.This is connected to a UPS that tracks the total power used by whatever is connected, and it looks like it is using about 75% - 85% less power than the old unit.UPDATE @ 6 Months: The unit has been running 27/7 for 6 months now, and has preformed flawlessly.  The only reboots have been for Windows 10 updates to install.
