Summary: I really like the machine. Mine came with Win 7 Pro for this price. If you can find one with that go for it.
Pros: Quiet, very quiet, small, easy to upgrade, powerful PC for the price. The E8400 is a great processor. 4 SATA plugs so could do one external. Room for a second Hard drive. With an adapter to split the power possibly three if you would leave one not secured like I do with a SSD.
Summary: I've been using an old computer with Windows XP, and after the support was cancelled by Microsoft, I figured it was time to upgrade to something more reliable. And I wanted to buy a computer with a large Harddrive and also one which worked with Windows 7, as I wasn't too fond of Windows 8 and 8.1, when I tested them. I also didn't want to spend too much for a computer for home use, as I use it mostly for emailing and downloading a few things off of the internet.
