this is what i have in my htpc:
AMD phenom 9850 with bf92 heatsink.
4 GB of DDR2-800
onboard 3300 video ( later 4350 or 4550 video card)
2 x 1 1 TB Seagate HD
1 x 160 GB seagate
1 x 250 GB seagate
2 x m780 HDTV tuner
right now i am putting 2 x tuner on 2 pcie 1x slot. i know that is correct. the heatsink is just touch the top of the cover. if i am not using any graphic card, can i plug one of the tuner on to gfx slot or not.
