Thanks for the suggestions!
I'll go with the 400 watt, and the blu-ray combo drive.
I'll stick with the 8gb cuz it's not that expensive (<$20 diff) and I really want it. I couldn't find the 8gb version of the 4gb memory you linked to at Newegg, at least, but I'll look around for it.
I've read some reviews saying the stock heatsink/fan is a little loud and/or whiny. The Big Shuriken 2 and its quiet PWM 120mm fan shouldn't have that problem. I suppose that I could install the stock one and test it out first, but having little kids I'd like to get the hardware installation done and in the cabinet quickly. So, if I install the first one and then decide to swap it out, I have to wait for it to ship, arrive, do the install, etc...
Any opinion(s) about the noise/sound of the stock fan vs. the Big Shuriken 2? And, the stock fan is short enough to fit under the blu-ray drive, right? (If I'm not getting any benefit from the change, then it's not worth the cost, but if it does make it quieter, my wife will probably be happier...).
And, if you've ever used this Mobo with a Big Shuriken 2, do you have any opinion about whether I'll have any problem installing it, or fitting the memory (I'll only be using 2 slots if 2 of them are blocked...) and PCIe card (for the Ceton)?
As for the IR receiver, are
(I can't yet post urls)
(search for HP MCE remote IR Receiver and find two by Gu Cheng Fulfilled by amazon, one with 6 reviews, one with 17, but both seeming to be the same hp ir receiver + remote).
the same thing? (At $22, it is a few more dollars than the top ebay link, but with Amazon prime I'll get it quickly, and probably with less hassle.) Is there any advantage to the Flirc (which is a similar price to the amazon version of the HP IR receiver)? Only problem I see with the flirc is that I'd need to get a longer cord so I can mount it somewhere visible to the remote.
Thanks again for your help!
