Hey guys! I've been looking into creating a Home Theater PC for a few days and I'm not totally sure where to start. I think the most intensive thing I'll need it to do is play back HDTV video files. I've built a few computers before and I'm not opposed to doing it again, but I'm on a limited budget and unsure if they can be built or bought cheaper. Are there any boxes you'd recommend? I'd love to keep it in the vicinity of $300 or less if possible. Thanks!
