Hi Pwrs! Looks great. Would you please share details about your fan-forced cooling?

hi and thanks pcb. I dont actually have to much information on the cooling as this was something that was going to get thrown away. it splits into 4 parts and have alot of surface are inide. My colleague told me it was good for about 1000 watts. The plan is to use a fan from this review Recommended Fans | silentpcreview.com , hopefully i can manage to get a tolerable dB level

Very unlikely if you are building something from Nelson Pass.

that depends, could be something designed for ~100-150W per channel output, that would need to cope with ~1000W of heat =)

I think that some of the very big Pass products can get to around the 1kW maximum output level. Certainly they get to well past 1kW of dissipation.
