Ok, we have the HDD figured out, but what about everything else? Here's the system requirements for n track and fruity loops.
n track: CPU: Pentium III-700 or better, 256 Mb RAM
FL:Windows 95/98/Millenium/2000/XP, Latest version of DirectX and DirectX-supported video & soundcard recommended, 30 MB free disk space, Minimum Pentium II processor required; Pentium III processor or higher recommended, 16 MB memory required; 64 MB memory or higher recommended, Boxed version needs CD-ROM drive
So they aren't too demanding. I was thinking 512mb RAM, winxp, dvd burner(the kind that burn dvds and cds), some firewire/usb ports. As for a cpu, soundcard, videocard, and mobo, I don't know anything about those. is there anything i'm forgetting?
