I've bought 5 PCs from this vendor, much lower QA testing than any other (I've only bought about 40 of these from Amazon, so not a high sample rate.)  But,  this is the first vendor that I've found that shipped obvious defects;  Multiple machines have 2-4 USB ports burnt out; one, the plastic casing on the SSD was split by the screw that holds it in the bay.  Won't buy from this vendor again.  The price is good, but for the same or a little better, you can get higher reliability.
