Having had previous "Bleeding Edge" experiences with computer hardware and software over the years- is one big reason why I decided to wait until the 64 systems and software appeared to be out long enough that software, hardware and systems experience could get a grip on it. I think we are pretty much at that stage now, but will be certain that the CompUSA guy who builds my machine (just the basic stuff, I can add the rest) will stand behind it. They have been really good to me in the past and they have a major regional facility only minutes away from where I live. Plus the guy has already built quite a few for businesses and the government so seems to have a handle on what works well. Also- he's giving me full flexibility on how it will be built- it's not a pre-installed OS Box solution. Also the prices he is quoting me are quite a bit lower than what I've heard other people paying as well. This is because obviously CompUSA has huge volume access to lots of this stuff now (as I mentioned earlier, I picked up Maxtor 200GB drives-7800 RPM, 8MB Cache- for just $129 from them). Not pushing CompUSA for everyone- I just think I happen to be in a good place where the store does huge volume and has significant technical resources in-house. I wouldn't want to do something like this over the phone. I like face to face, eyeball to eyeball contact and try to ask enough good questions to feel like I'm getting honest answers from him. Also- while I'm getting a low ball-park price from him, I plan to use the best RAM and components available, not what is the cheapest price. I'm willing to spend more if I'm getting reliability and stability in a system.
