Due to the current market with parts, Your best bet is through a direct manufacturer or a place like Costco. My Last desk top I called Dell's efurbished department (which is located in the USA, if you call Dell's normal number you will get someone in India.) I called the refurbished department, and told the guy what I was looking for, and really what my budget was. The guy told me almost all the unti, have never actually been opened or used but are returns that can't be sold as new, but pretty much are. The guy gave me an incredible deal on a I-7, 16gb ram, ect all the stuff I asked for, and it was under $500. Pricing one new, even when using $300 off coupons were closer to 1300 with everything I wanted. Worth a try. For new, I think costco is the way to go, and they double your warranty length, and will let you return if you have any major issues.
