Ok, then forget the DDR566, and get standard DDR400/PC3200...it was just a suggestion. You can downsize the hard drive and pick the optical drives you NEED. Secondly, it depends on what kind of things you will use this for. Will you be gaming? If you will then you need a better card. If you won't, then even a GeForce PCX5300 will get the job done or an X300 SE for that matter.
NO OFFENSE, BUT IT IS MEGADETH...NOT "MEGADEATH"! Just call me Mega instead, I like that too.
