I also have purchased the g20 from best buy. The first time I bought one i went with the i5 8gb model. Thing crashed so much, had some weird start-up issues where it would get stuck on the asus screen right on boot-up. I returned it and purchased the more powerful i7 model with the 16 gigs...so far no real issues. I noticed the fans act different then the last model, sometimes it sounds like ocean waves when its updating and bothers me. Its still very quiet and doesn't get to loud. I guess what im wondering is if i should purchase the warranty from best buy on it. I also own a Lenovo y50 that is awesome haven't had any issues worth it but for some reason this mini desktop makes me want to purchase a warranty, last one i had was so "sketchy" for lack of better words. Also i noticed if you do all windows update then Nvidia Drivers the computer works alot more efficiently.
