Hello,
My question is can I put a new motherboard into an hp envy desktop (Intel version). I have heard that large name system integraters (dell, alienware) use proprietary motherboards with standoffs in different locations than standard manufacturers. Is this the case with hp? and if so would it be plausible to drill new standoff holes into the case?
