Thanks

The SST-NJ450-SXL would give me more space inside the case. There is 1-2mm height left with the G3, very-very tight overall.
But yes, a HDPLEX 200W Linear Power Supply and a HDPLEX 200W DC-ATX are in my mind right now for an upgrade.

Thanks.
Yes, for this use the G3 is just ok. Its ventilation never turns on while playing music or movies.
It's ok until I get some proper linear PSUs for the whole PC. I've already get one external linear power supply for the STX2 and I'm really pleased with it.

I have built my first HTPC, or totally silent pc mainly for audio, but also for video (occasionally). I build in my old components into a HDPLEX 2nd Gen H5, so to CPU is now on passive cooling :) Gigabyte GA-Z97N-Gaming 5 i7-4785T 2x8Gb G-skill Asus Essence STX II ssd 120gb Evga G3 550 (silent mode)...
