Nephasth:
Any progress?

useing the parts your selected and some very sofisticated math "aka" http://extreme.outervision.com/psucalculatorlite.jsp you only need about a 50w P/S. So you should look into a external P/S http://www.mini-box.com/picoPSU-160-XT will be more than enough for a basic streaming PC and it would free up a ton of space

Hi Guys,

Sorry for the long lapse in the project and updates.  Had a series of personal emergencies that took presedence over my toys.  I'm about to get back on track with this project in the next month ... + or - ....

...and for low power usage being a requirement, 400w seems like a bit of overkill...

Nephasth & Kalars123 - I think that the estimations of 50w are a bit off.  My processor (AMD Phenom II x2 550) can pull up to 80w by itself. (figure 90% usage as a base = 72w) and that doesn't count the motherboard, hard Drive, case and heatsink fans, USB controllers ect).  The external PS's that I was able to find weren't up to that kind of power and I enough clearance to be able to unlock an additional CPU core or 2 if needed further down the road.

The reasons I decided on a 400w
1) I was able to find a small form factor 400w PS that is virtually silent and fits in my case ... just barely
2) The higher percentage of a PS's capacity you use the more heat it puts out.  Using the Power Supply Calculator page listed below, my system at 90% capacity requires a 188w PS.  400w > usage multiplied by 2.  With such low usage the PS fans can really help pull heat off the motherboard and cool my case. 
3) I've read that the higher percentage of a PS capacity you use the more likely you will experience power fluctuations which can lead to system component damage/failure. ... in theory. As I'm less than supremely confident in the quality of the PS (Not familiar with the brand) I'd like to have some extra watts floating around.

Vigo - Thanks.  I hope my project comes out to be half as good as yours.  Great Work BTW

BurgerKingDiamond & Nephasth - I've not given up on the idea of getting a working BlueRay in there yet.  I did look at hanging the MoBo upside down and it looked like it might work but I'm worried about hanging that kind of weight from the top of the case.  I've had to do quite a bit of cutting and am a little worried about stability.  Though I did end up with a spare Genesis and Sega CD model 1 ...  I think I'll be hearing the dremel tool in my near future...

Thanks for the suggestions, please keep them coming and I'll post my progress as it happens.

Nephasth:
Ever finish this one up?
