$500 build for the parents

(im asking for a build with OS and without OS)

APPROXIMATE PURCHASE DATE: within the month BUDGET RANGE: $500 before shipping

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: internet, banking, ...very moderate gaming aka old command and conquer games etc

PARTS NOT REQUIRED: keyboard, mouse, speakers, maybe os(see above)

PREFERRED WEBSITE(S) FOR PARTS: newegg COUNTRY OF ORIGIN: usa

PARTS PREFERENCES: none

OVERCLOCKING: i might, just for fun, depends on cpu choice... SLI OR CROSSFIRE: nothing needed beyond onboard gpu so no

MONITOR RESOLUTION: need a monitor  

ADDITIONAL COMMENTS: i may or may not be able to get a copy of windows so i need a options for w/ and w/o OS. id like the pc to be pretty stable for use over the next few years (aka good psu)

currently their oooollllddddd dell single core demension 3000 is looking to be retired.

500 bucks is the max, spending less would be nice but i dont want to cut many corners.

here is what i came up with:

this is w/o OS

if i need the OS i figured we could drop down to the dual core amd cpu and only 2 gig's of ramm

they would like a new montor too. right now its a 15" crt...

if there are some prebuilt

options out there that would save some cash, in your opinion, let me know. i figured building it myself would yield better results..


thanks
