If need more memory, can use rather standard DDR-400MHz CL3 Non-ECC UnBuffered 184-Pin SDRAM DIMM from a 4-5 years old PC.

The following module will work for sure:

1GB PC3200U-30330 - hynix HYMD512646CP8J-D43 AA
Dell: SNPJ0203C/1G
Compatible: Dell Dimension 3000, Compaq Presario SR1055CL

This module might work as well, most likely:

1GB PC3200U-30331-E0 - Samsung M368L2923CUN-CCC 0635
Dell: DJ0203.D
Compatible: Dell Dimension 3000
