BC-S might be worthwhile for the geek at home
Just on side note:
I have spent the last 1.5years working on all those systems at IBM in Germany and really like it!!!
BC-E is a bit of a waste of time, the BC-H a really neat piece of kit for the pro, and the BC-HT great for the telco environment, but the BC-S might actually be really worthwhile for the geek at home, but definitely better than a bunch of pizza-boxes!!!
granted, it is a bit pricey, (well, the blades are, but there are frequently good offers (yes big blue actually at times has really cools sales offers!!!)
Of course itś not something the gamer makes use of, but in terms of storage and being able to build your own infrastructure (vmware works really nice on those blades). and with the current ability to a gross of 18TB of disk-space (12x 1.5GB SATA), which can very nicely be shared amongst the blades!
And if you really want to do some serious calculations, just ad a QS-22 (Cell processor). the I/O sucks, but the number crunching is second to non!!!
not really surprising, that it being used for the fasts HPC in the world (Roadrunner).
Or some robotics. controlling four 3D robots and doing some motion recognition on a single CPU at the same time: I don know how an X86 system would cope (no matter if it was single dual or quad core).
Any company that needs a basic blade environment, should think about this.
The blades are hot, the kit really nice and is extremely flexible!
One just has to love it!!!
I don work for IBM any longer, but that stuff just rocks!!!!
