In general doing anything to an oem prebuilt with whitebox parts other than storage and memory is a potential recipe for disaster.  I recently opened one of these and it has a few weird features.  One of them is the light on the back which stays on for a while if the thing is unplugged, but drains the PSU and motherboard capacitors if the power button is pushed when the thing is unplugged and the light goes out.  Good chance you will lose that feature. Also those mount holes could look right but be off by a millimeter and the thing would no longer fit a different case.

A better plan.  Those things are dog slow anyway. Ram a Dparted key on one today and it was ever so much faster.  It was a win7 machine.  I suspect the thing is ready for a Linux.  It just can’t cope with the new stuff well anymore.

I've been down this rabbit hole since I got one of those boards for silly cheap a while back. No one, at the time, made the correct adapter to plug it into a standard ATX power supply, also the cooler mounting is non standard and uses the case itself to screw the cooler down to. I ended up just extracting the Windows 8 Pro key that was stored in the BIOS to get my money back out of the stupid impulse purchase.
