I had a totally gawd awful experience with Axion, my worst on the net by far. Frustrating, especially as I decided to order from them based on resellerratings and anandtech.
Ordered complete system for them to assemble as per my specifications. They take the order, bill my card and claim to have shipped it. Weeks pass and no system. Calls to 800 # (which is usually busy) reassure but they are never able to give me a tracking number. Finally THREE weeks after my card was charged, they acknowledged my order was never processed, much less sent. They promise it will be in my hands 2 days later.
It arrives 5 days later without any documentation. It is misconfigured, a cheap power supply substituted for the one I had paid extra for, and the motherboard is damaged. How? They put a chrome orb on an abit K7 Raid, despite warnings from places like anandtech, and despite my specific instruction not to use the orb. They scratched the capacitors.
I returned the whole thing. Never even plugged it in. Took another 2 months to get the purchase price back from them. They had my money for 3 months and I had squat.
Courtious, but incompetent. NEVER have them do any work for you. (If I had not known what to look for I would be struggling with this system today.) Perhaps they are ok if you want a boxed part (I'd never trust them though). Don't count on any prompt problem resolution, and you cannot believe anything they tell you.
Go elsewhere. You can't be saving enough to make the risk worthwhile.
