Just to clarify I ordered the tower with 8 gigs of RAM, not the SFF (small form factor) with 16 gb. Also, this one was sold by Refurbanana.For the past couple of years I've been using a cheap refurbished HP dual-core small form factor that I like a lot, but it runs Windows 7. Not only that but the video card, 5.1 sound card, and USB 3 card I installed had to be narrow with short mounting brackets. It also has a small power supply putting out only 225 or 250 watts, with no way of upgrading it.Stepping up to a tower with a quad-core i7 is a big change, especially with all the room inside for expansion.Mine came with a 240 gb SSD, a 3 tb hard drive, USB 3.0, and a DVDRW, which is great. Packaged reasonably well, the unit looks almost like brand new. Even the new USB mouse and keyboard are good enough to keep for backups.I've spent more than a day tweaking Windows 10 while installing a lot of my preferred software, and this thing keeps plugging away so far. Now it's time to order a good video card and 5.1 surround sound card to make this computer complete.Unless I experience some sort of sudden hardware failure this PC is everything I need to keep me happy for the next few years.*Disclaimer* I paid full price, and don't sell my opinions for trinkets and freebies.
