    Yes - up until the point it may break.
    Kalniel: "Nice review Tarinder - would it be possible to get a picture of the case when the components are installed (with the side off obviously)?"
    CAT-THE-FIFTH: "The Antec 300 is a case which has an understated and clean appearance which many people like. Not everyone is into e-peen looking computers which look like a cross between the imagination of a hyperactive 10 year old and a Frog."

    for all intents it seems to be the same card minus some gays name on it and a shielded cover ? with OEM added to it - GoNz0.

    Re: ram voltage

    Depends, some RAM such as OCZ allow up to 2.15V if I remember correctly. It still doesn't void the warranty (technically I dunno if they can actually tell if you "broke" the RAM by overvolting).

    I reckon if the RAM has sufficient cooling (heatspreaders at least) then 2.1V should last, 2.2V-2.3V would probably require some sort of active cooling over the RAM though. I have a Corsair Dominator fan and it cools down the RAM loads. However it's slightly "whiney" so I just have it in a box atm and also because it blocks the red LEDs on my Crucial Ballistix Tracers haha.

    Anyway, in short: it should be ok provided that the RAM doesn't overheat. Heat ends up destroying the RAM.

    That depends entirely on the modules. JEDEC specify that DDR2 ram must withstand up to 2.3V without incurring permanent damage, but their recommended voltage is 1.7V - 1.9V and there's no guarantee that any given stick of DDR2 will operate correctly outside of that range...
