I'm not sure what these are called. I have a SATA HDD and want an
enclosure for it to connect via USB2 to a PC.

It's probably going to be called a "USB External Drive Box".
You can get them with either SATA and PATA internal connectors an also
some with both, for the greatest flexibility.
There is a lot of crap ones out there:
Small boxes without fans that overheat the drives.
Slightly larger boxes with fans that fail/go very noisy, very quickly.
IMHO, it is worth paying the extra for a quality one, which will
probably have a temperature controlled fan.
One thing that you might consider is eSATA. Unsing an eSATA box,
together with either a PCI card or faceplate with SATA external
socket(s). I have found them far better than USB. YMMV.

How important is it to have it in a box?
I got one of these, arrived this morning, just tried it out -
http://www.dealextreme.com/details.dx/sku.10113
They do a couple of other similar models.
This one connects SATA and 2.5in and 3.5in PATA.
It's cheap, quick, and convenient. Just plug everything in and you
have a bare drive running as a USB external drive. It took longer to
unwrap the parcel.
The only downside is that it takes a week or more to come from Hong
Kong. Oh, and it came with a USA style kettle lead, but I am not short
of UK kettle leads.

If you connect a 2.5" SATA or PATA to it does it still require use of the
PSU? I just got a sealed Formac 2.5" 250gb USB 2.0 drive from amazon for £
60 ex VAT delivered and one of the main attractions for me was its size and
also the fact I don't need to bother to plug it into a power source each
time I want to use it, its plug and play. In time when the novelty of using
it wears off the fact I don't have to go to the trouble of finding and
plugging into an available power socket will come into its own.

Mine doesn't for PATA. 2.5" SATA use the same connectors as 3.5" drives,
thus need an external supply (IIUC, I don't have anything that modern).

2.5" PATA drives use the same connection as 3.5" drives don't they? and yet
using a 2.5" PATA drive doesn't require the PSU, by this logic why would a
2.5" SATA drive need to use the PSU?

Nope. The 2.5" PATA connector has extra pins at one end for power (as
well as being smaller form factor). Thus the one cable provides power as
well as handling data.

The SATA drive still needs a power lead as well as a data lead to be
connected. The USB "dongle" doesn't have a SATA power outlet and so a
brick is needed.

Ah right, thanks for putting me straight. The type of adapter suggested
would probably be best used if your only going to use the drive(s)
temporarily, if you were going to use it as a permanent way of connecting a
particular drive externally you'd be better off with a case to house it,
this is particularly true of a 2.5" SATA drive.

These adapters are ideal for a temporary connection - eg
restoring/making a backup. I wouldn't use one for anything longer term
than that - too great a risk of damage.

I think it should supply USB power to a 2.5in PATA, as the drive
connector includes the extra pins normally used for power on a laptop.
However I am not in a position to test that at present.
However with such an arrangement, there is always the question whether a
single USB socket will supply enough juice. It can be touch and go.
Some 2.5in external units have a second USB plug, just to draw the extra
current needed. Remember a USB socket is only specified to supply 0.5A
The short answer - you would have to try it with your own drive to
answer the question for yourself.
