There is no onboard GPU. I specifically looked for on without. And this is going to be a hybrid core at the beginning. It will probably be a hybrid core for a while. It will go in the basement and run the entertainment center. Once I build our home theater room (hope to be complete a year from now) then it will probably move into there and I will build a media director for the TV that we are using now. So, this Hybrid will probably be a hybrid for a couple of years. I usually get several years out of a computer because I will repurpose them.
As far as PCI slots go, besides tuner cards and a NIC, what else would I need to put there? Honestly, I haven't decided on what tuner card I want to use. It is going to be either the Hauppauge WinTV-HVR-2250 (I have one in my MythTV and I love the dual-tuner/one cable thing), or a Silicondust HDHomeRun-Dual (it has dual-tuners and any computer on the network can access it, currently there are 6 computers in the house), or the pcHDTV-5500 (only single tuner but it's supposed to have better Linux support. I was leaning towards the Hauppauge because I've used it, I know it's quirks and can work around them, It's dual tuners on a single slot, and it's PCI-Ex1 (which the MB has four of). Also, we don't watch TV on the other computers but they do access the music and other media so the Siliconedust/s network availability wouldn't be an advantage. The Hauppauge is in lead (for me) over the pcHDTV because of the dual-tuner/single cable/single slot. I like neat installations including cable runs.
I welcome any opinions on tuner cards as I have not completely decided yet. I was going to do a different post later on but it came up here. (Thom -- you kind of talked about this before but I wasn't clear on your opinion).
So, having said all that, other than an additional NIC and if I went with the Hauppauge, what else would I use the PCI slots for? (serious question - no facetiousness intended)
