Fast, Quiet, lots of USB ports, NO USB 3, WiFi adapter doesn't work, but it does what I want. No problems with large monitor,I use VMware so the 16-GB is great. The HD is 2TB and while I am no fan of Windows 10, it has the Professional version.Replacing the Hard Disk is very easy, have already done that.For the price, there is no other computer I've found that comes close.
