I'm planning on buying the following and wanted to know if this is a good deal. I've been doing my homework but this is my first personal DIY computer. X-Dreamer Case w/350 watt PS Asus A7N8X-VM Motherboard w/built in 128mb video memory AMD XP 2600+ CPU Kensington 512 Memory WD 80gb 7200 8mb cache HD Samsung 52x32x52 CD Burner Keyboard & Mouse Windows XP 19" Hitachi Monitor All for $720.00 Is this a good setup ? Would you change anything without making a huge change in cash ???
