I think this has more to do with the refurbished small form factor business PCs eating up their market share as they flooded the market. I can get a decent i5 unit for $100and throw a $100 into it in upgrades and hit the same performance as their $300-400+ price range.
I found an HP SFF for like $60 at the thrift store with a 4th gen i5 and it was kitted out with more ram and a 250gb SDD. Perfect HTPC for what I do. I was shopping NUCs too.
I got this at my local overpriced thrift store and was surprised they didn't want a shit ton for it. This place will put ebay listing (not even sold) prices on their electronics. I think it came out of their office or something.
