This system is great!! I've read some reviews from people complaining about the performance and the look (used).  But when mine was delivered (fast delivery) I was very impressed.  It was also packed very well like they knew how much hell UPS puts packages through their delivery (& yes my box came dented and beat up and I was actually scared to open it to see it). The Keyboard and mouse are new but the case and monitor shows little signs of wear.  Inside the case is clean looking like a new system.  The WIFI is a USB dongle (not a card) but it has better range than my built-in wifi in both my laptops. CLEAN and UPDATED operating system ...again very impressed!! ALL specs are correct so anyone complained that this is slow need to be prepared to pay at least 5 times more money to get a faster PC. This performs exactly as a brand new "Intel Quad Core i5 3.2GHz, 8GB RAM" and I am pleased that I got more than what I paid for!!!
