Don't want to rain on anyone's parade, but our experience with these folks (Alienware) was not good. We ordered a system for my son several years ago as a Christmas present and it never arrived. The delivery people (Airborne Express) had taken it to the wrong house and forged a delivery signature -- not even very well. Neither they nor Alienware would admit fault. I don't expect them to give stuff away free, but we had all kinds of documentation attesting to the fact that we hadn't signed for the thing. At first they sent a replacement but then billed us a second time without notice, and refused to remove either billing.
Fortunately, in February, when our neighbor around the corner got home from her trip she realized the box wasn't hers (a maid had taken it in without paying attention to the addressee) and alerted us. Alienware did reverse the billing when we sent the unit back. But they were not nice about it at all. . . . . .basically accused us of lying to get a second one free with no apology when we sent the one back.
Anyway, we won't buy from Alienware again, nor any company that uses Airborne Express for delivery. Just our experience, of course. YMMV.
