Thanks for all the nice words. Yesterday i tried upping the volts to 2.2 - shouldn't have done that - fried the MB and possibly the CPU

No matter what i try, it won't boot - the led-diosplay on the MB wouldn't show any codes, and the PSU just powers the fan down after a fwe seconds... tried it with the incase PSU - it won't do anything at all - not even power up. i have an extra 250W - it powers up the PSU only, and the RPMK on the fan falls as it was going idle). the 12V line showed 13,5 just before i died - think that's the explanation...
any advices?
I have a MSI KIT266 Pro2 RU lying around, gonna put that in tonight, and se if it's gonna boot... I also have a spear locked XP1700 - gonna put that in too, to see if the MSI will boot with that, to se if the CPU is fried... other than that, things are fine here in Denmark... (very upset about trying the 2.2V!!!)
BTW: i know about the back - it's UGLY

gonna fix that with some sheet-metal i have lying around - should be nice and clean... and yes - it is the first WC setup, i've made with alle the stuff inside the case (was getting pretty tired of not being able to move it around...). and the fanbus on the front - gonna make a new plate and align them all - it's just difficult, because the front won't close, if they aren't in exactly the right place...
