1) Socket370's are for the Celeron PPGA's. Slot 1's are for Pentium 3's. It's not that the mobo is best "suited", it's required.
2) If the mobo specifies on board controllers, that means that they are built in. Notice that these are much more expensive mobo's? Basically, it's just like having the SCSI and the Ethernet card already installed, so you won't need to buy them.
3) This is a question that has been debated for a while. For now, the 810 and 820 don't offer much performance increase (if any) over the venerable 440BX. So the 440BX is a better value, plus RAMBUS sucks and is expensive.
4) Hmmm... Haven't heard of this.
5)The Mobo will come with IDE Cables and everything necessary to install it. Your case will come with everything else you need.
BTW, the mobo's you are looking at are kind of high end. You sure you need all that?

Do I need that much MB??? Hell I don't know. I know what I want, and I really dont want to spend to much (duh!!) but I want the best (Double duh!!!!!).
Right now I have a SCSI setup...(i.e. two SCSI HD's and a SCSI zip drive.) So I want ot keep the SCSI line up. The thing is I have a SCSI scanner that comes with it's own propietary SCSI card (Another card!!). At one point I tried hooking up my scanner to my Adaptec 2940W card but i couldn't get it to work) So now I read how the MB have the SCSI on board. Does that mean that I can hook up my SCSI chain directly to the board and not need the Adaptec card? (It'l save me a slot, that's for sure. THen again, how do I hook up my scanner (External device) to the MB???
Same thing applies to my Ethernet card. I have an external modem that goes to the ethernet card (LAN). If the motherboard has the propietary Etehrnet card built in, how do I get my modem to the MB??
That's part of my dilema...go with a MB that has none of these features and fill in the appropiate slots with cards (whish I'm trying to avoid) or get a MB with propietary devices (I.E. Ethernet, SCSI) built in and avoid the extra cards (but then what do I do with the external devices????
PS...Thakns for all the help. You have definitely answered more questions in a few emails than ASUS (Tech Support) did in a month...
