Okay here's some photos:

The bigger one is my older intellistation, it's obviously way heavier (the 50-pounder). The differences are: it doesn't have a back fender, there's no metal under the top handle (cheapo IBM, reminds me of iMac G3s), and it has a key lock instead of a little loop for a padlock. So IBM added more sophistocated and expensive methods, but also cheapening down on other things.
The insides are absolutely crazy, that funny metal side thing (I'm wondering if I should just take it out without putting it back in), the "dust buffer" I couldn't figure how to get off, I was going to clean inside there.
Here's an excerpt from the manual, the texts in brackets is my own, obviously.
The computer might come with an air baffle that directs airflow to the microprocessor (wait, MIGHT come with one? They ALL come with one, otherwise the computer would overheat). When you install optional devices, you might have to remove the air baffle to access some components.
To remove the air baffle, complete the following steps:
1. Press in on the tabs on each side of the air baffle. (I don't see any tabs, it's as coherent (or baffling) as the other "air baffle" on type 6225, which, didn't explain everything).
2. Lift the air baffle out of the computer and set it aside. (no ****?)

When I was cleaning it out, it had a lot of dust in the front vent, even remnants of a moth wing:

That's what you get for $300 I guess. The rest of the computer was cleaned out though, they just didn't want to get a migrane from figuring out how to remove the front bezel and whatnot.
