[conspire] Advice on Building a Computer

This is a request for help in reviewing specifications for a computer I am
building. It is based on a Tyan 2468 motherboard, also called the K7X.
The intended use of the computer is as a server and a learning
environment for me and a couple of other people. The MB is equipped with
two SCSI channels and I want to put five to seven drives in the
system to continue learning and experimenting with RAID
and LVM. I want to use quality components as this computer will be kept for
quite a while.
The MB is...
Some general information:
* this is an extended ATX motherboard. It's big and
intended to be a server. I have the two AMD Athlon processors and
memory for the system.
* I have a large case for the system, a Lian Li V1200B Plus II
that can hold eight or so drives.
There are two particular areas in which I would appreciate
your review: drives and power supply.
The motherboard is a model number S2468UGN
with a UPC of 635872-006449. This has two SCSI interfaces,
SCSI A and SCSI B and is specified as Ultra 160 SCSI. I
believe these are 68-pin interfaces rather than 80-pin because
the 80-pin interface is, as I understand it, more often used
for hot swappable drives and I don't think I have that in this case. I need
to verify that what is on the board is 68-pin.
I think I want to put two or three drives on each interface. Thus I would
need two ribbon SCSI interfaces like, I believe, this:
and some number of SCSI drives like this 68-pin one:
Does that sound reasonable?
This extended ATX motherboard requires an ATXGES power supply.
There seem to be two ways to do this:
a) buy an ATXGES power supply with the proper connectors
b) buy an ATX power supply and obtain (probably via eBay) an adapter cable
An example an ATXGES PS is http://www.power-on.com/atxges.html at about $80.
An example of an adapter cable is
rcloZQQssPageNameZRC0021?_trksid=p1638.m120 and these are about $20 plus the
cost of the power supply.
So, any thoughts or recommendations would be appreciated.
To recap: I think I need:
* power supply and possibly adapter cable
* SCSI ribbon connector for the drives
...as I already have:
* CPU's and memory
I have someone who can help me with the assembly of the computer.
Thanks for your consideration.
