My opinion (for what it's worth) is that the on-board Intel video card is crap, and the 512mb of RAM could be limiting.
As for not being able to build your own within your budget, I would say you didn't try very hard or you live outside the US. I spent about 2 minutes at www.newegg.com and just quickly picked an Asus NForce3 MB, Athlon 3400+, 1GB (2x512mb) of RAM, an NVidia GeForceFX5200 (slow, but cheap, and better than the Intel card), an Antec case, a 250GB Maxtor SATA HD, and a Lite-On DVD+-RW dual layer DVD burner. The total (with shipping) was $685.18. Of course you should throw in a floppy drive and speakers, so that's another $40 or so, which makes it the same price as the Gateway system. The Gateway system also comes with Windows though, an 8-in-1 card reader (don't know if that matters to you), and a TV tuner. The NewEgg system on the other hand is slightly slower (3400+ vs. 3500+), has double the RAM, a better video card, and a 50GB larger HD. If the 8-in-1 card and/or TV tuner are important to you, then you could get a 200GB HD (like the Gateway system) and a video card with a TV tuner and an 8-in-1 reader. If having Windows included is important to you, then you should just buy the Gateway system cause it'd be cheaper. Anyway, my point is this: if you _really_ wanted to build the system yourself within your budget, you can build one better & cheaper than the Gateway one.
Note: NewEgg system does not include a monitor (but the Gateway system doesn't include one either, even though there's one in the picture).
