low cost game PC station

I want to make a low-end entry-level game PC station for my son during the summer vacation. It's about HK$2073 with the following config :

1.  Asrock P4VM8 mother board                 - HK$355
2.  Intel Celeron 2.4 GHz CPU                 - HK$528
3.  Geforce 64 MB AGPx8 display card          - HK$220
4.  80G ATA-100 hard disk                     - HK$420
5.  52x Combo CD-ROM                          - HK$290
6.  256M DDR 400 RAM                          - HK$190
7.  Case and power supply                     - HK$200
8.  Floppy disk drive                         - HK$40
9.  Keyboard and mouse                        - HK$100

A licensed copy of Windows XP Home will add extra HK$700, hence the total cost amounts to HK$2773. Hmmm.., I shall make the PC available by next week.
