Chill out. No need to curse.
Going with a prebuilt doesn't really save you much money in the grand scheme of things, because the parts go bad earlier. And without that expensive more-than-90-day warranty, you're out of luck when your stuff goes bad. It really isn't that hard to understand.
So instead of you being able to replace your parts if something goes bad later on down the pike because they are more UNIVERSAL, you're stuck with a hunk of junk that you can't fix unless you shell out lots of money, and at that point, you might as well buy a new one. That's the whole grand scheme of prebuilts in the first place.
If money was a real issue here, they wouldn't be asking for a build with 700-800 bucks, and even so, I still made it under the initial budget by well over 100 bucks. So money apparently is not an issue. I'm sure he'd rather have a good machine with good parts instead of saving maybe 50 bucks.
Trotter, that was a nice find on a cheap GPU by the way.
