^ long answer, that card would likely have the powersupply (and it's a really shitty one in those kinds of PCs) running at max making it much more likely to fail and take everything else with it.
To boot they usually use really old motherboards in there, probally from last generation, meaning the PCI-E lanes will be half as fast. That won't stop you from doing it but you certainly won't be able to add another one in there with that motherboard.
and to square it all off, the damn thing might not even fit in the case /shrug
oh just took a look at the specs of the thing, it's a piece of shit and shouldn't cost more than $300,
case in point I just marked it up over at PC partpicker using the cheapest parts I could find that work and still came out under their cost. you even get stuff that actually has name brands associated with them as well instead of a nameless power supply and motherboard company no ones ever heard of.
