Hello, I just started with Western Govenors University (WGU) and I am going to switch from networking to security as my major. In the interest of computer security, I was introduced to Backtrack Linux.

My question to the forum, is what is the suggested computer hardware configuration for the Penetration Testing with BackTrack (PWB) certification?

My dad sent me his old system. Here is what I presently have running with Ubuntu Linux 12.10:
> Micro ATX tower
> 800 watt power supply
> 2 x RealTek Gigabyte NICs
> 4 GB RAM
> 1 TB 3Gb/s SATA hard drive
> NVIDIA GeForce 660 Ti (2GB)
> 3 x 23 inch Acer Monitors (and yes it does work on all 3 monitors: 5760 x 1080 resolution) on Ubuntu
> Intel Duo Quad-Core with DDR2 RAM with FSB 1333MHz
> DVDRW drive
> Running Ubuntu 12.10 (64-bit)

My question will this be enough horsepower for the PWB test or should I upgrade?

Options: considering a different Mid-Tower chassis with motherboard upgrade and expansion to NVIDIA GeForce 660TI Quad SLI - but that may be a while since I tight on the cash flow right now.

Thoughts, suggestions?
