That is a lot of overkill for an HTPC. A low end current intel dual core or even a Celeron is plenty sufficient. Even for a strong system, not much reason to go above an i3. Ram...again, fancy memory is overkill. You just want something stable, which you should find in any name brand piece. No need for performance RAM. I would probably go with 8gb if you use windows MCE simply because it seems to be the sweet spot for x64 windows in general as well as the sweet spot price wise. 4 will get the job done though. This isn't a gaming rig where stepping up processing power, tight memory timings, and overclocking will make a difference. The key to HTPC's is efficiency. A certain level of hardware will handle the video/codecs/resolution you desire, and with that figured out, the aim should be going as low power (less heat) and quiet (low power/less heat a big factor) as you can. Additional processing power beyond what it takes for the codecs/res you use really doesn't do anything for you. As far as video goes, that is dependent on if you are going to set up any post-processing and at what level. The on chip video of the newer intels is plenty for normal hardware decoding of 1080p video...and if you get into post processing, how much muscle you need depends on what level of processing you want. For SNES emulation...that level game system/emulation needs next to nothing in relation to todays processing power. You should easily be able to run that on even a Celeron with on chip video. Power supply...depends on what you decide for video really. Again, this isn't a gaming machine, so you don't need some $200 huge jiggawatt unit. To put into perspective, you can easily only draw 30-50w at load from the wall on a basic sandybridge or newer HTPC without even much effort placed into efficiency. You also need to consider the efficiency range of the power supply as well. For example if you got some fancy 750w quality PSU for future headroom for whatever reason, and end up with a system that only draws 50w, you may not be using enough juice from that psu for it to operate efficiently and probably would pull less from the wall with an average 300w unit then that fancy high dollar 750w. I'd just go with a lower wattage quality unit, unless you put in a relatively powerfull video card, then bump it up as needed. As far as the vid cards go....when they put up requirement such as recommending a 500w PSU for example......that isn't some sort of code for high end 1000w power supply. Those recommendations are based on a relatively heavily loaded system using a cheap no name over rated PSU. Therefore, say the max draw of that particular card is 250w, and you estimate the rest of the system to draw 50w at load, you could comfortably use a quality 400w psu and be just fine even though they recommended 500w.
