@illfindu thanks for the reply. For some reason my sig didnt show with all gear.
Shuttle Sn68s2 specs:( http://us.shuttle.com/barebone/Models/SN68SG2.html
The PSU, PCI-e stock Shuttle gear. The only thing internally from Shuttle I changed was the 92mm fan. I went to a better air moving model with 3 speed options so I can control the bg noise when in production.
I used to have a little trouble firing up the shuttle from dead as I think I'm pressing the power consumption. It says 250w but I know its at least 350w as one of their techs told me they have tested it successfully up to 350w.
The other option I could do if stuck is upgrade to the 300w psu which can do at least 400w.
