Noob build - Help with PSU + Case

Needs: Smooth PVR function via Myth 0.25 backend, play 1080P mkv BR rips, snappy, relatively quite, small. It needs to be able to be Velcro-ed to the back of a 40" LCD like my ATV 1. All data is served from a server, this is just essentially a front end.

So far I've settled on these - wouldn't mind some critique. I see advice in the stickies for 8GB SSD's, but am unable to find anything under 32GB.

CPU: Celeron G530 $44 @ Amazon http://preview.tinyurl.com/aqmzv9f

OS: Openelec or XBMCbuntu

I'm struggling with finding a case and PSU that is small enough to fit behind a TV. I also am not sure if I need a CPU cooler. Some of the cases I've looked at say fanless. Is there a go to case in this situation? I do not want or need any optical drives.

I've looked at the M350, but do not see a strong enough power supply to go with this.
I've also looked at the Morex 557 Universal mini itx.

What about something like this? It has a 200W power supply http://preview.tinyurl.com/bcjtgby

Thanks, and sorry if these are dumb questions
