i wish to add two more hard drives for a grand total of 4. i have an new seagate 120gig 7200 rpm drive excatly like the one already installed and i also have another 40 gig drive similar to the maxtor 40gig i am using as my master. i also wish to add a hard drive controller. there are a few concerns i have and would like to nail down some details before i waste time and/or money.

concern 1.)
i only have space for two hard drives in my current tower. i have a few ideas of how to overcome this. i could get a new case with room for all drives. i have a spare tower that is completely operational aside from having an operatiing system, i could install linux and use this computer as a file server for my home network in which case i will need to replace my router because i do not want to sacrifice speed. i could customize my case to accomedate two more hard drives(new power supply needed?).
2.)
i want to be sure i purchase the right hard drive controller. i think i want the two 40gig drives set up so they are not mirrored, i want fast access and it will also be 80gig total space. the two seagate 120gig i think i want mirrored. that way my music, movies, and files will always be backed up internally. or maybe visa versa, i do like the idea of 240 gigs of hard drive space.

lets throw some ideas around and see what we can come up with.
