I'm glad I saw this thread...here's my dilemma:
I've been waiting for XP Media Center Edition to come out so I could build a HTC. Of course, they then announce that you can't get it unless you buy a system. THe Alienware is almost exactly the system I was going to build (the Shuttle case), but with a few major differences:
Mine would have a Radeon AIW 9700 Pro, and a Sony DRU500A DVD burner. I would probably scale the processor back to a 2.4. As of today, my system would cost about $1700 to build. I could get the Alienware for $2000, and with it I get Media Center edition, the special remote, and obviously, a warranty. I don't want to buy their system and swap out the video card and DVD burner, since those 2 account for almost $800 of my system price. I will probably end up building my own...I was just kicking this back and forth today.
Decisions, decisions...
