If you are not looking for a laptop some of this info will be different.
I went with an inspiron from the outlet store. Here is the trick:
1> Patience is required to get a good deal. The equipment goes in and out regularly.
2> Whe you find something promising, add it to your cart. (no one else can take it -- it reserves it for you) If you find something better add it and remove the old.
3> as long as you do a search every 10 mins, the one in your cart stays there.
So go here:
http://outlet.us.dell.com/ARBOnlineSales/topics/global.aspx/arb/online/en/InventorySearch?c=us&cs=22&l=en&s=dfhPut the following in the fields:
Min Memory: 2000
Video Card (MB): 256
min hard drive: 120 (I prefer more, but this is a minimum)
For Operating System I recommend Windows Hom Premium, but you can leave that as "All": if you want.
Pick an Intel Core 2 Duo (I would suggest a minimum of 2000 Mhz (2 GHz) myself)
Then click the "filter results" link
If a list comes up, click "price" to sort them.
on the list you will see a link with 8 characters (seemingly random) on the right side for the ones it pulls up. Ths give more detailed specifications. If you find one you like, click the link and verify the following:
