What I wanted to know was can I add more hard drives when I get it. The base system only comes with 250GB and I need at least 1TB but Dells upgrade to 1TB is really high ($300). If I could and I installed the program on the added hard drive would it make a difference then installing it on the hard drive with the OS on it? Would the X3034 CPU be enough.
You can easily add hard drives yourself. The T110 Chassis has room for 4 3.5" drives, so minus the pre-installed 250GB, you have room for 3 more. Installing on another hard drive will depend on the what hard drive you buy. A 7200RPM drive will generally be faster than the slower RPM green drives. The X3440 is a great processor, and should be fine.
