Pros Nice hardware.
Cons Max of 16GM RAM. Factory they did not set up the Intel RST correctly and the user manual doesn't explain how to. Can only attach one external monitor. Using the Dell AIO 2720 as an external monitor I was only able to get FHD, not QHD. See summary.
Summary I own the 2720 without the Blu Ray ODD and I also own an iMac 27" late-2012 model. You can attach two external monitors to the iMac and have a total of three because it has two thunderbolts (display ports). You can not do this with the Dell XPS AIO 2720 using the HDMI and DP. The Dell AIO 2720 has the same native resolution as the iMac 27", but when I used it as an external monitor via the HDMI in port it only displayed a max resolution of 1920x1080. I tried it with my MBP 15 mid-2012, i7-3820QM, GT 650M, my iMac 27, and my gaming tower, i7-3770K, with two Radeon HD 7970 in crossfire. Has anyone experienced the same or were you able to get QHD resolution using the Dell AIO 2720 as an external monitor? If what I have written is correct, maybe CNET should do a better job in reviewing computers.
