Some people aren't reading the same article I read. (I added the bold)
About pre-built hanaho cab:
If you have the bucks to burn -- we're talkin' $4,000-$5,000 and beyond here -- you could simply buy a high-end, ready-to-go package.... It's a great, albeit expensive, turnkey solution.
About the X-arcade cab kit:
"It serves as a decent compromise between costly, ready-to-play arcade cabinets and the build-it-from-scratch approach. ... and retails for $999.95.
So, while convenient, this product is presently an enthusiast-only purchase based on its cost. "
About ready to build kits in general, dud says it's more expensive than BYO:
there's another, more user-friendly alternative [to BYO cabs] -- ordering an assemble-it-yourself arcade cabinet kit. That's the plan for this feature since time is as much of a concern as dollars.
And dude never quoted a price for a true BYO cab:
Those on more limited budgets may want to consider buying cabinet plans from a vendor like Game Cabinets and then build a unit from scratch. Another option is to purchase an old arcade cabinet to refurbish and retrofit.
Maybe gamespy edited the article before I read it (they do that sometimes), but if not, the article is already saying what we know: BYO & refurb-ed cabs are cheaper than ready-to-build kits, which are cheaper than pre-built brand new cabs.
Now, I agree part one is very much an advertisement for the X-arcade kit, but that's how most journalism works.
