I've used Dell PC's in the work place for over 15 years, including this model. I was looking at replacing an old one and thought I'd check Amazon for a 990 and I'm happy to report after one month, this is a really good deal. If you are looking for a fast (not blazing fast) reliable PC for home or business, you can't go wrong with a Dell 990. It came with Windows 10 Pro, 500 GB SATA drive and 8 Gb of RAM.  After registering Windows (you can do it online), I checked for other pre-installed software and found Microsoft Office 2016 which requires product purchase for continued use. I noticed the installed version was 32-bit. If you run MS Office you'd want to remove the 32-bit version and install the 64-bit one. There is no other third party software installed which is great news, since you don't want the clutter of software you don't use. I do recommend buying it with a SSD drive (250/500 GB) and 16 GB of memory. If you run dual monitors, add a video card. A few more dollars but worth the cost. If you do not upgrade anything at all, you'll still end up with a pretty good solid computer for $200.00 dollars. After applying Windows updates, I proceeded to install all the apps I usually run and is running really well. If I buy another Dell PC, I will make sure it is from SkyTech.
