1700 is probably too much for that setup...

===================================================
For a NON-gaming pc Just maya and photoshop/adobe products
===================================================
Graphics card: NVIDIA 8500GT – 512MB : $99
CPU: INTEL CORE 2 DUO E4500 – 2 X 2.2 GHz – 2MB – 800FSB $170
Motherboard: some base level gigabite - $120
250 gig main operating system raid edition hd - 130 <-- they would probably have to order them in very reliable for operating system
500 gig hd 32mb -main storage drive - $160
powersupply: COOLERMASTER 460W EXTREME POWER - $80
ram: 2GB 800MHz - $110
Sound card: CREATIVE AUDIGY OEM - $50
some $90 case
Around $1000
maybe 100 for vista... id rather xp but yeh
maybe they will charge 50 to put the custom pc together
---------------------------------
But on the other hand if u buy the $1700 computer and it breakes then u can just take it back and they would know how to fix it...
But if u need renders to do, u can take it to uni and use the Uber awsome pc's

thats my 2cents
