I've ordered from ATIC 2 or 3 times. The prices were great, but the customer service is horrendous, and very hard to understand them if you don't speak their native tongue... which obviously isn't english.
I ordered a complete compute from them once (minus monitor), and when I set it all up, it wouldn't boot properly, beeping however many designated times it is saying something wrong with the RAM. I fiddle with it, reseat it, test it in other computer, nothing works. The RAM is bad.
I ask them for help, they tell me I have to send EVERYTHING back for them to test it. I send it back, 2-3 weeks later after many phone calls asking what was up, they tell me the RAM is fine, and they're sending it back.
I get it back, and it's still not working! So I take it to an independant store in town and they test the RAM. Their conclusion the next day? It doesn't work. So I send it back to ATIC asking for a replacement. I send it back and one of the first things they tell me? Yeah, that's right, the RAM *IS* bad, we'll replace it.
So I think it was about 6 weeks before I got my working stick of RAM.
I've decided not to buy from them again.
