I am looking to get a ATC-201 style case, however, i am getting confused with all the different models i am seeing, which as far as i can tell look like the same case. ie.. These are examples of model numbers i have seen.

ATC-201B-SX2 - seen on sharkey
ATC-201C-SX2
ATC-201B-SXK
ATC-201-SX2

Do they vary at all or are they all the same case?

The reason for asking is that i want to get the case which has been mentioned in this months extreme gaming PC review on this site... it is the Coolermaster ATC-201B-SX2 but i cant find that exact model here in the UK for sale anywhere, i can only find the others stated, so are these others the same or are they different?

If anyone can clarify this for me i would be very grateful.

Cheers
Jon
