What are the minimum specs that I'd need, CPU, Motherboard, and GPU (if not on-board), to smoothly RIP Blu-Ray ISOs to the hard drive, and then play them back via HDMI? I don't want anything "scaleable" or "more than you need" as that just seems like I'd be wasting money on the wrong parts of my home theater. (What good is a great processor that doesn't get used?) I'm not planning on doing any encoding of files, no gaming, no TV tuners, etc. Most recommendations are for solid all-around machines, but I'd rather build specific hardware for a Blu-Ray jukebox, and free up the extra cash for more hard drives in my NAS. Thanks.
