Of course, no problem!
Height of the opening is ~26.0 cm (top to bottom, not taking the small mid-bar in account)
Height behind the opening till underside 5.25" bay is ~27.6 cm
Underside of the drivebay has a slight bulge under it (right at the front the height will be 1-2mm more)
The 240 Rads I've got fit exactly...need a slight bit of shimmying to make the 'turn' sorta say, but it fits.
Hope this helps!
