Can anyone recommend an enclosure (preferrably in the UK) that doesn't have problems with the Benq DW1620?

From what i've seen on forums since i bought this drive, it seems to be one of the best so I'd really like to keep it and get another enclosure that will work with it.

If all else fails, will the Benq work perfectly if I install it internally?

Does anyone know if it can be fitted vertically?
