dont buy from Hong Kong, or , like me, you will be sending your dead unit back there to be repaired. Look for one in your country, there are plenty of dealers out there.
as far as the system goes, i think it is "ok" if you dont want to build your own, but as far as components go....
dvd rom $45
40gb laptop drive $100
so figure almost $600 for a system you can build for about $350 plus a case
I like to build em myself.
My system cost me about....
512mb pc4000 $75
250gb 8mb cache $145 (rebate)
24x laptop CDRW Dvd combo $70
Morex case $70
and I think you will find it a far superior setup than a production unit!
