I cant say much about those units ( don't know anybody who has bought them ), however, some people I know have custom build similar units of their own. Your biggest concern with something like that is going to be software compatibility with your movies. I have some blu-ray's that just wont work in my PC because the firmware the disc was authored with isn't compatible with the player, but the disc will work in a stand alone player. I had problems with My PC playing movies through my 72' HDTV. Blu-rays would work fine but DVD was choppy and sluggish. I recommend just sticking with the standard home theater components, but thats just my own opinion. You have a 7k budget, why are you looking for cheap hardware deals?
