Pros: Works out of the box without issue. Wanted more RAM for a virtual machine I'm running off a Windows computer. No problems. Just make sure you pay attention to the difference between DDR3 and DDR3L.
Cons: None
Pros: Screws work, Solid fit all around, All holes align properly
Cons: None that I can see.
Overall Review: Wound up using this one at work to swap out a hard drive and keep a computer up and running. Worked perfectly when using a normal 2.5'' non-SSD, SATA drive. Was pleasantly surprised that all the holes aligned properly, both to the hard drive itself and to the computer's hard drive bay without any machinations.
Pros: I've had this for about a month now and I'm very pleased with it so far. Good price the for the hardware. Generally works out of the box. Just make sure that all updates to drivers and Windows are installed after the initial startup. I use this for home office work and general computing, so the processor is a fine fit and the lack of a dedicated video card doesn't bother me. Right now, everything is moving along fine, so I don't feel the need to immediately upgrade to a solid state hard drive or add memory. The system has the headroom to do this later when the time comes. So far, this is turning out to be a pretty solid workhorse, which is exactly what I need.
Cons: Had some issues with the dual-band wifi card and needed to force it to only use the lower frequency. This is more an Intel (wifi manufacturer) problem than Acer's. Some initial hiccups with my HDMI monitor coming out of sleep, but this seems to have shaken itself out after driver and OS updates. Some bloatware that can be (mostly) removed easily.
Overall Review: Recommended for anyone looking to do general office application or student work at home, but not for PC gaming.
Pros: No complaints. Cheap and quickly adds wifi to some of the older computers I'm working on. Basic, but effective and seems to hold up. I've had to manually install drivers for Win 7 from the company website, but works after initial setup.
Cons: None. Does what's asked of it, finds the networks I need and doesn't lose the signal.
Overall Review: Installing drivers from the manufacture's site can be interesting. When I downloaded the file, it came down without its .zip extension. It took me a while to understand that I was dealing with a zip file, but I solved the problem by simply renaming it and adding that .zip extension. Unzipped and worked fine from there.
