Somehow the zombie PC continues to lurch along (albeit rather worryingly, constantly accessing the RAID array even when it doesn't appear to have any reason to) - but the good news is that my shiny new PC has already been put together by the tech-wizards at PC Specialist and is in testing. Fingers crossed it will be sitting in my bedroom by lunchtime on Saturday, gobbling up all manner of software and drivers voraciously.
I can't wait to see what a 64-bit, Windows 7 Pro system runs like on a 3.2GHz 6-core processor with 8GB of RAM. Should be... SPEEDY.
