This is a great and fast desktop in a really small package. Uses only 15 Watts when not number-crunching.
You can find my other auction on the other big e-auction web site for the same price but without the WiFi because the other site charges more fees. I mention it because you can see I'm 100% positive feedback and just starting here with zero feedback. You can do a search for i5-3470 on the other website and see this is worth at least $180.
Keyboard is NOT included.
Windows 7 Pro 64-bit (OEM recovery disk and 2 drivers are included with this on a DVD)
Intel 4-core 64-bit i5-3570s 3.1 GHz
500 GB Hard drive.
4 GB RAM
Power supply included
Windows 7 Pro Installation Notes: Using the Windows 7 Pro 64-bit OEM recovery disk, I did a fresh install and activated it as "Genuine Windows" via Microsoft's website using the original COA sticker that is on the case. You will be able to do the same with a new hard drive and the DVD I'm including if this one fails. I installed all updates, Internet Explorer 11, the WiFi driver, the USB 3.0 driver, the graphics driver, and the network NIC driver for wired LAN. I then tested the sound, the CD-DVD RW, and made sure no yellow trianglular "!" warning symbols were in the device manager list. Recycle bin is the only desktop icon. There are only 6 folders in file manager. I did not go into the BIOS.
WiFi is a USB type that works up to 30 feet. $10 discount if you do not want the Wifi.
I can add 4 GB RAM (Crucial type from Amazon worth $30) for $20 more.
