Quad Core, 12 GB RAM [EDIT: 16GB], SSD. I transitioned to this from a 7 year old laptop.  Night and day contrast. I have all the Office Suite programs open, plus Dragon NS, web browsing, Asphalt 8 etc. Takes the CPU utilization from 1-2% up to maybe 12%.  I love this thing!There was an odd issue where the DVD drive could read discs but not detect blanks for burning. I let Felix know, he immediately sent a replacement.  Problem solved.For how powerful this PC is, it is tiny, and never gets hot. I don't even hear the fan running.  Buy one of these. You won't be sorry.update: I bought one of these in May 2020.  It is still going strong.  Meanwhile, my wife's laptop is showing signs of HDD failure.  So I checked on this machine on Amazon, price was down from ~$330 when I got it in 2020 to ~$180!  So we got another one.  Just got it in last night.  Everything is set up, plus dual boot MX Linux.  DVD drive is good, haven't checked if it can burn disks yet.  If you are thinking of a budget PC that will wow you with performance, this is the way to go.
