Hardware for hacking?
Until 2 weeks ago my computer was an AMD Athlon system running at 650MHz with 320MB PC100 99MHz RAM and a 10GB and 20GB IDE 5200RPM drives with dial-up capabilities and !!-ATI vid card under 8 years old-!!
Now, it's an AMD Athlon X2 6000+ 3.0GHz with 2GB DDR2 800MHz RAM, 250GB SATA 7200RPM HDD, NVIDIA GeForce 6600LE (soon to be SLI'd to a 6800GT when I get an ATOP adapter) onboard LAN, 5.1 Hi-def sound, dual monitors (triple if I get an LCD) a SUBWOOFER and a very precise GE optical mouse, and a 10 yr old 104 key keyboard >_< (replacing that soon)
The first one took 6 hours to crack a pass, the second took barely one hour. Obviously, it's easier if you have a faster machine, but really anything will work. For example, at school to get an admin hash, all I had to do was stick in a Gentoo minimal CD, mount a flash drive, and cp mnt/hda1/windows/system32/config/sam to /mnt/sda1/logs/
You can do anything you need on a monochrome T-21, if you like, but better hardware make things easier. Hacking is all about making do with what you have; if God doesn't give you the root password, you must find another way to get it.
Hope I didn't ramble too much, I didn't mean to make a speech.
