You can get the slim version with wifi, new, on amazon for $4 less.
looks like it has a 240g SSD instead of the 500g 5400rpm hard drive as well, certified rewnewed, but SSD makes it worth it.
Not if it only supports 16gb max. It’s gotta be 32 or more now days. I maxed my built pc from 10 years ago out at 32 and when you are moving lots of media files from the pc to network, the more mem, the better.
