Asus motherboards are known for decent support. Chances are, that carries over to their laptops, as well.
I currently run a Dell 9100. Honestly, I hate it. I'm looking to sell it and pick up one of the BF laptops, and get a powerful desktop. I've previously owned an iBook, and although I was pretty angry when the motherboard fried, it was otherwise a wonderful laptop. (They actually volunteered to fix that problem for free; however, because I had already replaced the LCD, they refused. And the LCD broke because I dropped it from about six feet. The motherboard problem only really applied to the G3 iBooks; the G4 versions lack this problem.) I also fix computers, including laptops, to make a few extra bucks; I just had someone give up on their D600 because it just had hte motherboard fail after two other parts were replaced, and it was'nt worth repairing. (600$ for a motherboard is crazy, if you ask me.)
For the record, it's rather silly trying to run Autodesk Inventor on anything less than a 9700 and a gig of RAM if you want to do anything serious. And CATIA looks to blow Autodesk Inventor out of the water. (Heck, IBM just partnered up with Dassault to sell it with some of their high-end mainframes.)
I just reccomended these same people the Dell Z33A for a replacement laptop. Although I've had no more than glancing looks at Asus laptops so far, I've yet to hear of a problem with one; their older laptops also have a reputation for quality. I'd buy one myself if I could afford one.
Also, off topic, I don't like Nik either.
EDIT:
I can't find any info on Catio. If you're referring to Dassault's Catia CAD program, it looks like a beast. I've tried to learn Inventor (another CAD program suited to mechanical things, like robots) and it requires one heck of a powerful system. If you're running CATIA V5, you'll likely be wanting something with some serious power.
The system requirements only technically require 1024x768 resolution for the monitor and 512 megabytes of RAM. However, 512mb is likely a miniumum. Considering that the latest edition has been ported to Sun's BLADE server line and HP's FIREGL workstation line, a 6600 and a 1.86 ghz Pentium M might only barely be enough.

A FireGL or a Quadro might be nice; however, I'll warn you, any laptop with one of those is likely to weigh a ton and have abysmal battery life, in addition to being quite expensive.
Edit #2:
After checking about online, ASUS Actually has iffy tech support. As a rule of thumb, they generally have tech support go through the vendor. If you buy your barebones from a place like Newegg, they'll just RMA it and you're set. Also, the documentation's supposed to be good on ASUS products.
If you buy your computer through a good vendor, like JNCS.com, you would go to them for tech support. JNCS has a very good rating, and being able to get a 3-year warranty is always nice.
Yet another Edit:
A good place to get a barebones looks to be Axent Micro. They sell the Z71v in bareones form for 740$.

They also have a good review from resellerratings.com, especially in the area of support.
