This is almost certainly1/4 BSP. EldonJames makes 1/4BSP to 1/2" ID tubing barbed adapters. As I remember, these had a very large ID (don't have one to hand to measure). You can get them at mcmaster-carr (and most likely other places like usplastic). I think they were $3 or $4 for a package of 10.
These fittings were not o-ringed (although you could add one if you like). I just add a tiny dab of teflon paste to the portion of the thread that is not going to come in contact with coolant and have never had one leak - but I'm not dealing with high pressures, being a watercooling-for-quiet kind of guy

Oh - these fittings are nylon, which means that you can cut them off (careful what you do with the leading thread, use a knife, not a saw) to control how far in the fitting goes. Pay attention to interior flow issues as a fitting end protruding too far in might hurt (depends on the wb).
Finally (and IMO, of course) these EJ "single barb" fittings do a really good job sealing to tubing as the tubing can "relax" back to its natural ID once past the barb.

[edit]
If this block is completely hollow and the inlet is above the CPU contact area, try using the block with the (new, longer) BSP fitting screwed all the way in. Older swiftech blocks, which were like this actually benefited from the inlet stream being a bit more focused in this area - which was something you could do by brazing/soldering an extension on to the fitting - but you've got BSP, so you can just thread it in a bit more...
