Looking back over this, there's a few things I forgot to mention...
- In addition to being rather large for a TV component, the computer's fans are also quite loud. I'm thinking there might be a way to tweak BIOS settings to get them to run quieter, but for now, if this thing is going to be part of a home theater, it'll have to be noise shielded somehow.
- I said I'd mention more about KDE in the above post, and I will -- tomorrow. Same with why nVidia was a good choice.
- The device which will take up the remaining PCI slot is the video-in card.
- Yes, I am currently living with my parents again, but it's only temporary, really… Trust me, I wanna get out of this place as soon as I can, and getting a decent-paying job with my soon-to-be-acquired certification is an integral part of that plan.
