I have 200 computers, have had 500 or 600, ( see my website
kidbots.com ), and would give you the same advice I give
everyone else. Get a generic case and power supply, have
a local shop put in a generic motherboard ( ASUS, MSI etc.),
and put everything in a slot ( AGP and PCIX video, PCI for
everything else. ) Have lots of ram slots for future upgrades,
have a ZIF socket for the CPU, and put in the best you can
afford and make certain that you can add 1/3 to 2 times faster
in the furture. The case and power supply are re-useable,
the motherboard is upgradeable with better video (the most
important single thing today is a fast video card with
ever increasing amounts of video ram on the video card),
the sound is upgradeable in a PCI slot, -- onboard
Ethernet LAN at 10/100 is ok, and is usually sufficient,
as is onboard USB, and onboard 56 K modem which is now only
used as a FAX machine at 14.4 in any event. With LOTS of
PCI empty slots for upgrades you can turn off any onboard
devices and use an upgrade card in any event. I have seen 8 slots on a PCI machine...
Serial ATA harddrives are normal on any MB, and 40 and
80 pin ATA are normal on any MB for CD and DVD devices -
make certain they are there, and that ALL onborad devices ( if
any ) CAN be turned OFF in the BIOS ! ( Some motherboards
have onboard devices, but no way to turn them off if you
want to upgrade! ).
The GENERIC, standard sized, standard slot, Motherboards
and Cases are best, since at any time you replace parts
and upgrade.
HP, IBM, DELL, CompaQ, Gateway " Sometimes" use more or less
standard devices, but like the a1210n I am working on now,
it has an ASUS board that ASUS denies it manufactures,
with a proprietary BIOS chip with HP-only features, and
HP highly modified XP ( 8 Gigibytes of HP modifications !)
and although the ram, the video, the CPU etc are upgradeable, I cannot put in "real" XP or any other
operating system, since ASUS refuses to supply a "REAL"
BIOS that does not use the highly proprietary HP startup
sequences... Close, but no cigar.
If you stick with generic boards, supported on the web with BIOS updates, with all components upgradeable and replaceable,
you will have a machine that is not obsolete in 6 months,
that no one can ever improve or work on. My brother just got
a DELL, where DELL left off the 35 cent AGP plastic slot
holder so that you CAN'T upgrade the video from onboard
to 8X AGP, even though the board's BIOS and circuits are
there to do so! - When I called them, they said to upgrade,
you have to buy another entire DELL computer... (because of
a 35 cent piece of plastic they deliberately left off. )
Have someone ( or 2 or 3 people ) you KNOW who have been working on computers for a while,check out
any computer you are about to purchase FIRST... !
Go into a couple of local stores and TALK to the technicians if you can to get a sense of what is available,
and do your homework! A little bit of research can pay huge
dividends in the years to come...
Good luck
