but if I did, it would go to house payments, utilities, etc.
But if you did want a b*lls to the wall, *ss kicking, high octane dream system. Go to any PC Webstore, find the fastest AMD CPU, and motherboard, slap it into a large ATX case, use SCSI hard drives and controllers, and use mutliple hard drives via a switcher device (Tiger Direct has them, but I forgot the name of them) to select your OS to boot from them. Get that LCD screen you've been waiting for. Buy XP Pro, Windows 98SE, Red Hat Linux, and eCS.
Or heck, why not, get that dual 1Ghz G4 Mac! Then just run OSX and Virtual PC to run the PC stuff.
