The Swiftech kit is great, but the rad is a bit lacking for the i7. They use a low profile(allot slimmer than regular) rad and while it does the job, it could be better. You might want to check the W/C forums here and get help with parting up a killer custom job.
As for first time w/c.....everyone has to pass that hurdle. One tip that I have is read up and ask questions as you're doing it. Having an understanding of the entire process is key
