From what I remember of the current DIY newegg kits, many of them are just fine. More of a giant combo package (to save money) made up of 4+ components rather than one of those "barebones" kits that are usually consisting of cheap components.
So yeah, it depends what newegg DIY packages you are talking about. The relatively new DIY packages (there are tons) at newegg are generally just big combos rather than the usually crappy "barebones" kits you can find all over with the cheapo generic cases, cheap mobos, etc.
If any of you regular posters that buy from newegg often haven't checked out their DIY section, I highly recommend it.
