Do a search for Novatech in the Forums. I can only recall one bad report personally and that was from someone who bought the wrong thing. It was his fault and everyone that responded told him the same thing but he seemed to think it was Novatechs fault. It wasn't, the guy clearly had no idea what he was buying and bought the wrong thing, it would have been different if he'd asked Novatech and they told him to buy this item but he didn't he just bought it on line. Novatech offered him a refund but not the postage as it wasn't their fault but this guy just wouldn't accept it. Total twit in my opinion.
Novatechs after sales service is to me second to none, all the other companies could take a lesson from them.
I've bought 5 barebones systems from them and all have been perfect as has everything else I have bought from them. And if there is any problem they will do their very best to sort it out quickly.
I always buy from them if they have what I want, I only go elsewhere when they cannot supply what I need. Highly recommended.
