I didnt know you were an IT geek too haha... Well done on the 1st go success!
Simon built a pc for me must be quite many mths ago now. It has a see thru case and you can see the neon cables of blue and yellow when it lights up, very cool! 
Yeah, I worked as an analyst for 10 years....I have no idea how many PC's I've built over the years but now I'm looking for temperature as an issue....I've had SO many parts fail on my over the years, including harddrives, that I'm rather paranoid now. When I saw that one of them was running @ 70C, I knew that I had to resolve it or lose the drive. This case really was the solution. As of now, the hottest the drives get is 48C, well below the problem temperature of 70C. I would love to build a clear case but I worry about the internal temperature. Plus I don't know if I could get the internal cables to look good....can you upload a picture of your case? I'd love to see it....
