Any reviews on the new swiftech kits?
Yeah, martin of martinsliquidlabs reviewed it and several other did too. It's a good unit, though it seems like early models were plagued with some QC issues.
I have a H110 (dual 140mm) closed loop system on mine, and I'm pretty happy with it for what I use my computer for. I have the PWM Noctua fans turned all the way down, and it keeps things cool enough for me.

after reading eth0s' words, I dunno if I will try real water cooling now...I was under the assumption that water cooling had come a long way since the early days and that maintenance was very minimal and that risks were also minimal...seems not to be the case at all
There are risks with CLCs too. Look at posts where they burst and took out components in systems. With what you spent on an H110 and four Noctua fans, a custom loop would have been a great alternative without a ton of risk as long as you take your time and double and triple check that you're doing things right.
Most of the cases where I see something went wrong are user error. They did something like forgetting to tighten the compression fittings down all the way and to retighten them for the first week or so, forgetting to leak test before turning the computer on, or other things like that. You're putting water near electronics, so there's always risk, but there's a ton you can do to mitigate that risk.
