or you could just buy a ready workstation from alienware. they let you have all you would need for maya. either in dual xeons or dual athlons. you just need to customize them to suit the 2 gb of ram and probably get rid off somethings you dont really need (e.g. no need to buy a scsi raid, unless you want to do a lot of video editiing). also they come with quadro fx - and it is hard to buy them alone and built a computer out of single parts with a quadro.
