This is a nice little machine to use for either light computing or as a home server for various tasks.  The 4GB of RAM is very difficult with work with, and you'll probably want to pop in at least 8GB.  I was hoping to be able to just pop in one additional 4GB SODIMM, but unfortunately my M73 came with two 2GB sticks, so I had to buy an 8GB module, bringing it to 10GB.  Also, despite being a 7200 RPM drive drive, disk I/O also feels sluggish.  It could still use an upgrade to an SSD, which would probably make it relatively zippy.I'm fine with repurposing and reusing things, so this being a renewed device didn't bother me.  That being said, it was missing some of the screws, both inside and out.  The power button on my unit is not the most responsive.  The AC power adapter is also not the factory one, so I don't know about the reliability and efficiency compared to the original.  I didn't expect a mouse and keyboard with it, but they're usable.  It was all packaged very nicely and safely for shipping.  The fact that it came with a warranty is surprisingly welcome.All in all, I got what I paid for, and it's serving that purpose nicely.
