XGI is a newer company, only a few years old. My guess is they were the only company Terrasoft could get to produce the cards with the special firmware required to work with that custom implementation of Open Firwmare (open source version, SLOF).
Chances are they went with an older version of the platform for better support with their software and costs. A side from their PS3 clusters, this is their first forte into a real workstation / hardware solution.
I think the system will be an awesome performer. They have been doing PPC Linux for years and I am sure they tweaked it enough by now to make it a solid option for that market. I am definitely a fan of OpenFirmware based systems (mainly sparcs, todays G5 will be my first Mac with it) so I might concider this Terrasoft solution in the near future.
I do not particularly know the benefits of openfirmware, I do know the benefits of firmware in general over BIOS. Is the main point to avoid control like I am sure Intel has over its firmware implementation's that MS refused to support in Windows? Though I am sure the performance will be commendable it is still in essence a Quad 2.5 G5 which I could not see competing against a Mac Pro or other similar workstation with Linux installed. The only thing that makes that price compelling to me is that an SAS RAID controller is expensive which I am sure is a large part of the price.
Don't get me wrong I love the PPC platform and know the benefits of RISC over CISC I just question putting such an old CPU in a new computer. It would be like using original Athlon 64 X2's or Pentium D's (not Pentium Dual Cores). Especially paired in a workstation with a unknown video card I would just be more comfortable with a Power 5/6 and a Quadro or FireGL GPU.

I don't think they make G5s anymore at all... in fact, I think G3s were being manufactured even after they stopped with G5s (though I could be wrong). The only PPCs being churned out right now, are I believe G4s, though perhaps even those have stopped.
IBM is definitely still making POWER chips, though, if that's what you mean... and their new POWER6 chip is a real monster. Kind of too bad Apple isn't able to use a G6-version of the POWER6.. that would scream.
I am pretty sure the Power 4's are still being produced, don't the XBox 360's use Power 4 variants. Heck I do not know if they still do but until recently Motorola was still making 68K chips, possibly Freescale still does.
And the Power 6 would be a G7
. Even though the Power 5's were out I think before the Intel announcement Apple never incorporated them. Probably due to price, power consumption, IBM unwilling to make a Desktop counterpart and/or that we would by now have unbelievable powerhouse G7 iMacs and Powermacs while pushing 2Ghz single core G4's in Powerbooks and iBooks
