parts list for my new PC from Newegg -- roll your own and save

I want to replace our 6 year old dinosaur P4 system because it is slow
compared to the newer stuff. And it's been upgraded to its max specs.
I priced Dells on their website and was unimpressed. For about $450
(including shipping), I could buy their basic system, but it's
handicapped with a crappy Celeron with low L2 cache, crappy graphics,
one gig of RAM, and just a CD-RW/DVD combo drive.

But for $300 worth of parts from Newegg, I can get an ASUS mobo with a
fast AMD Athlon 64 X2 cpu, 2 gigs of RAM, decent video, ASUS DVD burner,
ASUS case, and all the other necessary parts. I thought the major PC
co's like Dell or HP would be more competitive in terms of the specs of
their machines, but I guess not. A friend just paid about $900-$1000
for an HP that has just slightly better specs than the one I am building
for $300. Home brew all the way, for me. "Roll your own" and save.

Here are the parts I am buying to build a low end machine that we use
for mostly internet (Firefox) and office apps (OpenOffice) and some
older PC games. Any advice or alternative recommendations for these
parts?
