From what I can see you have the 'R1' version. I don't believe they did R versions until they released the Triangle version. For you it would have been the Area 51 or Area 51 ALX which I believe had the fins on the top of the case.
The R / Revision number is CPU &/or chassis design-based. The initial releases began as X51 Aurora Area-51 sold w/an Intel CPU of its day; when new CPUs came out new R version 'names' were adopted, not unlike 1977's Star Wars, which only later became A New Hope. In the past we ID'd R versions by CPU or a new product launch, the exception is last year when the new A51 Triad 2.0 chassis differentiated the R3/R4 into R5/R6 (same CPU in a newly 'revised' chassis), while R7 (soon R8) ID'd by their newer CPUs
A51 released 2009 was only offered through one Intel CPU generation - discontinued - then redesigned years later, which earned an R2 moniker. When new CPUs released, we got R3 R4, subtle chassis redesign = R5/R6, newer CPUs = R7/R8
Aurora released 2009 was popular enough to earn CPU revisions, the Gen1 chassis' are R1-R4, the Gen2 redesign starts at R5 then newer CPU's give us the R6 R7 R8, where all models are ID'd by CPU
X51 R1 R2 R3 are ID'd by CPU
There is no R0, & we could not have an R1 until we officially had an R2, R1's are then of course retroactive. For support purposes, R1 versions are simply listed by their proper product name, where R1 versions seem to be a community-employee-owner convention, not an official 'revision name' or model. Your Bloomfield Intel 960 tells us you have an Area-51, from there we agree to call it an R1 (& if it's Space Black it's an ALX)
In otherwords the convention is X51, X51 R2, X51 R3. The idea of an R1 is a construct we agree upon ... ... ...
