As much as I would love to be able to build a new HTPC, it is just not in the cards at this point, cash is tight. I have an old PC collecting dust, and I figured it might just work. It already has windows 7 on it, the only problem is it's video card only has DVI outputs on it. My thought was I could pick up a cheap video card off of newegg for $25 with an HDMI port in it and bring it back to life as an HTPC. Maybe something like a Radeon 5450. The PC is an old E-6600 core 2 duo with 4 gig of ram. A few potential sticking point though, the Radeon 5450 is PCI-e 2.0, and my motherboard is an MSI 975X with PCI-e 1.0. Not sure if that would be a problem. Also, not sure if the old cpu is up to the task. For $25 it would be a cheap HTPC, but if it wont work I would rather not spend the money and effort on it. Will this work?
