The 20" iMac refresh uses an TN film screen.
I'm not sure what the current 24" iMac uses, but last year's model used an IPS screen.
Welcome to...errr...2007. The 20" iMac has used a TN screen since they got moved to the aluminum casing. While what you're saying is true, it's not what I was asking in the context of the discussion.
Not sure what could be causing the 6 GB RAM limitation - OS? Chipset? BIOS?
Well, that's what I was asking. What's the difference? The OS is the same build - you can install the retail 10.5.6 version from the Mac Box Set on any Intel-based Mac yet somehow some GeForce 9400 models will take 8GB and some will only see 6GB.
The Mini seems to be in the latter category
and yet the iMacs released the same day go in the former as evidenced by the fact that Apple supports 8GB. They support 8GB in the 17" MBP but not in the 15" MBP or 13" unibody MacBooks.
It's confusing. It's also a non-issue for probably 95% of all people out there.
More on topic, if you're going to pop $110 for an empty Mini Stack v3, you might as well pop another $90 for a 1TB hard drive
. With "only" 16MB of cache, a quick Newegg search tells me it's probably this Hitachi
as all other 1TB drives on Newegg are 32MB cache models.
