I'm working on building a HTPC and have a burning question that I've been wondering about now for years. Why doesn't anyone build systems that take, or can take, an external power supply (beyond the mini-itx crowd). I realize that temperature really isn't much of an issue as it can vent the heat directly out of the case. However, providing external power can mean:
1) Less noise (there is no such thing as a "truly" silent fan) -- even if the reduction is tiny
2) Strategic placement of the power supply depending on the allowable cable length
3) Potential to use DC power for powering the PC directly from a battery or solar power which would, essentially, make the power supplies 100% efficient (or closer to 100% than an inverter would be)
4) Smaller case sizes suitable for HTPCs
And these are just four of the obvious benefits. I realize I'm a n00b here, but I honestly can't think of any serious downfalls other than, perhaps, having a huge "wall wart" that would likely just sit on the floor somewhere.
So why do we not see these being created? Beyond that, would it be possible to create a "modded" power supply and case that would take such a beast?
