Build It: Half-Height Gaming PCs For The Living Room

By

PowerColor’s half-height Radeon HD 5750 launched a quest to build a tiny gaming PC. But things didn't work out the way we planned. We ended up building two half-height machines capable of cranking out playable frame rates, and put them both to the test.

Test Systems And Benchmarks

Our two half-height builds are detailed below:

    This is an interesting article and goes a direction where nVidia has no way to compete.

    I'd mod a case and mount my videocard horizontally.

    I've been using this one in my main HTPC for a couple years now at least. Haven't had any problems.

    that's weird, a 160w power supply powering up a 5570? (and you also intended to slap in the 5750 there?) did i miss something?

    Looking for a case like that is next to impossible - but for a 160W wow I never have though of that, it gives me another idea. thanks tom.

    Thanks for the article. I have a question, where do you find quality small PSU? If you want to go as small as you can, one would need to use small PSU. But it seems they are scarce in terms of wattage selection and brand, no where comparing to standard ATX PSU.

    Many small mini-ITX cases do include a small PSU, but what if you want to mod the PSU, or the included one breaks down? Falling back to standard ATX PSU would have to use a bigger mini-ITX case.
