You might want to go i3 for blueray playback, or else just throw a 5450 into your current build. I would look for a brand-name 300-350W PSU, rather than the freebie one. This shouldn't add any cost. $60 bucks shipped should get you a case and a real psu.
Blue ray's likely won't be an option with the integrated chipset. If you know the person you could always throw in a 5450 down the road for $40 and dropping (after rebate) If it is more of a customer arrangment, I wouldn't advertise this as Blue-ray capable. GKay linked a BR that also burns DVD's. As it's listed as OEM, it likely won't include software, someone else might be more help here.
edit: I didn't see the 880, I was still looking at the old nForce board. My mistake, this will be fine for BR playback if you go with gkay's board
Toms actually did HD3200 IGP/780G chipset testing for HD DVDs/Blu Ray in '08 so while the *recent/latest* IGP solutions are fine that GF7025 is not and Blu Ray would be a painful experience so ya 880G in a nice combo or even 785G ^^ http://www.tomshardware.com/reviews/amd-780g-chipset,17...
Thanks for the info guys, went with gkay's suggestion. I kept the case though, I know the power supply is crap. Is it possible to change the power suppy in that case with any atx psu? I have one that I am not using, but I dont know if it will fit in that case
