I'd be interested in hearing from people familiar with the ASUS P55TP4XE on
the following issues: 

	1) Securing the motherboard in a standard mid-tower case.  The 2/3 
           baby-AT board size hasn't fit very well into the last two cases
           I've tried.  Although I can match up enough plastic spacers to
           firmly support the board, I've only been able to match up one
           hold-down screw with the board.  The result is that the board
           wants to slip downward - and also from side-to-side.   I've 
           slid a couple of unfastened plastic motherboard attachment 
           clips onto the side of the board which shim it against the 
           back of the case where the periperal cards go - this helps...

	   Perhaps I've just made poor case selections - any ideas?

	2) Upgrading the on-board SRAM cache from 256k to a pipelined-burst 
           module.  This looks possible, but when I called motherboards
           intnl, the sales person indicated that I couldn't do this.
           I suspect otherwise - any clues on a supplier for the 
           PB module?

	3) 70ns memory and P100 - I know it says not to do this.  I made a 
           mistake and got 70ns memory anyways.  It works, but recently 
           I've been having some lockups w/no panic, etc.  This coincides 
           with placing the machine under much heavier loads (make world, 
           more users, etc.  2.1-R, 2.1-STABLE.)   Would it be plausible 
           that I'm having a memory problem (given that the machine was 
           a model of stability under lighter loads?)

 
Regarding the SP3G - I'm thinking about putting together a machine to thrash
with at home.  I have enough spare parts that I just need the main board and
a processor.  The spec sheets I've seen show it topping out with a DX4/100,
but then I've seen messages where other people are putting all kinds of
faster AMD processers in the SP3G. 

Any comments on what I should do here?


Regards,
-Chris
