first build questions

Hi I’m a first time builder and I have looked around for some decent equipment for a first time computer that will able me to upgrade a lot as I get more experience in building a computer on my own as for my first computer I just picked out somewhat cheap items to start off and that looks easy to upgrade in the future. So I was wondering if some one can take a look at what iv selected and let me know if they are compatible with each other and if you know of another item that is either cheaper and better or way better for not much more.

AMD Athlon 64 3200+ Venice 2.0GHz 512KB L2 Cache Socket 939 Processor – Retail $59.00

BIOSTAR GEFORCE 6100-M9 Socket 939 NVIDIA GeForce 6100 Micro ATX AMD Motherboard - Retail $59.99

APEVIA ATX-CW500WP4 ATX 500W Power Supply 115/230 V UL, CSA, TUV, CE - Retail $39.99

Western Digital Caviar SE16 WD2500KS 250GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive - OEM $74.99

CORSAIR ValueSelect 1GB (2 x 512MB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Dual Channel Kit Desktop Memory – Retail $84.99

SONY Black 16X DVD-ROM 48X CD-ROM IDE DVD-ROM Drive Model DDU1615/B2s – OEM $18.99

Btw thanks for taking a look at what iv selected I’ll mainly be using it to play games and surf the net so I also need a little help on selecting a gfx card but I don’t know if the one that is in the motherboard is good enough to start off? I don’t know what all iv missed so any ones 2 cents is very much appreciated.

-edit- im also starting out completely fresh I have no spear parts or any thing so if also know of a good cheap lcd moniter and all the other stuff I might be missing plz tell me –thanks-
