@Kitamesume - Taking all these things into consideration, spending a buck or two on a media player might be the wrong choice, since it will indeed almost exclusively be used for watching anime, and it indeed has come to my attention that a lot of groups have taken to Hi10p encoding.
Although my resources are not limitless, spending anything between $200 and $400 on a decent HTPC seems fair for an investment I will enjoy for years to come. When it comes to crunch, "complete" HDD Media Players aren't cheap either, and $200 for a media player that doesn't even completely do what I want it to seems pointless then.
A quick google taught me that there are virtually *NO* SoC Media Players out there that support Hi10P video encoding, so I might as well change this topic name to "Anime HTPC".
I am rather experienced at building my own computers, but those were almost exclusively gaming rigs, and I have little to no experience when it comes to building a HTPC. I can come up with some things to take in account, like silent yet decent cooling, but are there any other things that I should keep in mind?
I'd love to hear some pointers, as to what kind of hardware specs I should be looking at for optimal performance? It would be less than desirable to find out my freshly built HTPC is adequate only for Animé slideshows

Thanks for taking the time to reply!
EDIT: I'll make sure to check out the Ouya too, just because of the bang for the buck!
EDIT EDIT: Well, maybe not then...
