I'm sorry, this is ridiculous. If SGI was still in business and doing what they did so well* I could see $20k for a desktop workstation-class PC. Putting together the most expensive commodity parts and saying "That's worth it" is just crazy.
For what its worth, I just "built" a PC at newegg with these specs:
OCZ Colossus 2 Series OCZSSD3-2CLS960G 3.5" 960GB SATA II MLC Internal Solid State Drive (SSD) - $2,419.99
CORSAIR Vengeance 24GB (6 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 $164.99
Thermaltake TP-1500M 1500W ATX 12V v2.3 & EPS 12V v2.92 SLI Certified CrossFire Certified 80 PLUS SILVER Certified Modular Active PFC Power Supply $369.99
SMK-LINK VP6342 Black RemotePoint Wireless Navigator Suite $219.99
RAZER Black 7 Buttons 1 x Wheel USB Optical/Laser Mamba 2012 Elite Ergonomic Wireless Gaming Mouse $119.99
PLEXTOR Black Blu-ray Disc Burner SATA PX-B940SA-11 $159.99
Intel Core i7-990X Extreme Edition Gulftown 3.46GHz LGA 1366 130W Six-Core Desktop Processor BX80613I7990X $999.99
ViewSonic CD3225 Black 32" Large Format Display $669.99
SILVERSTONE Black Aluminum Crown Series CW03B-MT ATX Media Center / HTPC
$699.99
ASUS Rampage III Black Edition LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 Extended ATX Intel Motherboard $559.99
PNY VCQ6000-PB Quadro 6000 6GB 384-bit GDDR5 PCI Express 2.0 x16 Workstation Video Card $3,999.99
I deliberately chose some "outrageous" stuff, like a case with a 10" LCD monitor built in, a 32" "monitor" (really more of a TV that does 1900x1600), a $4000 "workstation" video card, and so on. Fine, it's not a "slim-line slot-load" blu-ray burner, but so what? Add $150 to the price to "make it fair", and so what? That's an insane workstation class system for well under $20k with features like the 2nd display on the case and whatnot. What, other than more hard drives could C=USA possibly offer? What? A "custom OS"? What Linux Mint distro will it come with then?
Let's face it, unless Barry is planning on opening a factory or at the very least having truly custom hardware built by big vendors for tight integration so you effectively wind up with a modern, SGI class machine and not a big gaming rig, I cannot fathom any workstation rig being worth $20k.

*=the SGI legacy lives on in nVidia and ATi cards as I am told many ex SGI engineers found work there, indeed some were headhunted prior to SGI's demise.
