shanizar: sorry I missed that you already decided.

I looked around but the only Swedish place i found that sold SEASONIC S12-XXX was
http://kylning.com but they didn't have S12-330.

Sorry I could'nt help you. Your rig is going to be very nice in the end me thinks.
ronrem: Thanks for your tip! I've thought about gluing some hard panel on the inside of the case, only the removable panel. But first I aim to reduce as much vibrations as possible. Still waiting for the rubber fan mounts. To be truthfull the computer isn't defening as it is now.

But there is a slight annoying buzz that is ever present. I think it's also because of air turbulence and that noise is enhanced by the case. So some type of dampening maybe. BTW the temp controlled fan undervolts just fine ronrem. The psu is on 7V all the time, no temperature control on them. The top ones still have the termistor and they seem to be working fine also. Full load (SuperPI and Prime95) gives me 42*C cpu, 37*C NB and 34*C SB temp on a non oc'ed AMD64 3000+.
[EDIT: found another place]
