Started with a Inspiron 530S 1GB, 250GB HD, Pentium dual core, base model
Dell offers an instant $390 off... best of the Dell discounts.
Starting price= $478.00
Processor... OK, upgraded to faster than the base iMac. Plus $40
OS.... Still only 32 bit, home edition... I upped it to Home Premium (as far as Dell lets you on this machine) trying to get closer to the full fledged features of OSX Leopard. Add $30
Memory on this build is 1GB to match iMac. $0
Monitor... you can keep your 22" analog... there is a reason for digital. Also your monitor does not have a webcam or microphone like the iMac... so I went with the 20" SP2008WFP with webcam and mic. It's both analog and digital. Extra $280
(Your 22" digital with webcam and mic is another $30 on top of the $280.)
Optical drive to include Roxio to meet the built in capability of the iMac, Plus $79
Graphics card to close equivalent of iMac's. Plus $60
Sound - Upped the sound but still no glass... $25
Bluetooth add $40
Wireless add $70
Firewire $30
Speakers - Add external stereo speakers to match iMac's built in... $20
Software - I should add ADobe Acrobat Standard 8 ($249) because the iMac can create and edit PDF files from any application... but I won't.
Setup - one month Phone support for setup... free on iMac $49
Data and App Transfer - One Time PC to PC transfer... unlimited included free on iMac... $29
$1230 base minus $390 coupon instant saving = $840.... total.
Not bad... for that you get a small limited expansion tower, no entertainment software installed, and lots of wires connecting everything snaking all over your desktop. And the aggravation of Windows...
A Firewire 800 card costs around $60.
