I have only built a couple AMD systems. I need another system for office tasks, video & audio disk burning, downloading files - NO games & NO overclocking. I would like to build a Core2Duo that I might someday stick some TV tuners into and turn into a PVR or media center. I decided to go Intel this time to keep the system SILENT via easy passive cooling, except for the power supply. An article on Tom's Hardware convinced me that looking at max wattage does not tell the story, because the tested Intel system completed tasks faster and used less power overall, thus generating less heat while providing a better computing experience.
Also, I have never worked with a micro-ATX board, so I might enjoy the challenge and the system might fit just a tad better next to my TV in the future (I am a bachelor, so I can get away with the indecency of a quiet Antec Sonata or Solo case in the living room). If there was an appropriate home theater shaped case that would even be better.
Although nothing is a strict deal-breaker, eSATA would be nice, ideally 2 ethernet ports, onboard video that works terrific when I eventually put in a high def DVD burner or a 24" monitor @ 1920x1080, perhaps HDCP compliant. 3-4 Slots for a sound card, 2 TV cards and a network card (if there is only one on the motherboard). I don't know if an unused PCI-E 16 slot can be used for anything other than video.
Your thoughts and recommendations would be much appreciated.
