Wouldn't notice a whole heck of a lot of difference between a 230 and 250 anyway.
As to whether or not they'd "clear", if you mean fit the screw holes, you'd have to check that yourself. If you mean whether or not they'll be in the way of other hardware, you'd have to check that yourself as well.
Even if we could answer this, the only way to be sure is to check the case and see. Online specifications are never 100% accurate and don't take into consideration what hardware you might already have in there. My latest build should have had room for the CPU cooler and the case's side fan, based on online specs and measurements, which proved to be inaccurate by 1cm. That's something you should consider as well.
