There are four different versions of the Optiplex GX620, the Mini Tower, Desktop, Small Form Factor and the Ultra Small Form Factor Computer.

Which version do you have?

If you have Mini Tower then forget about your choices, they look fishy to my and choose CORSAIR CX600M http://www.newegg.com/Product/Product.aspx?Item=N82E16817139048 more reliable, cheaper and modular.
If your PC form factor is smaller - SFF or DT, then you are out of luck, no upgrades here, sorry.

Do you have anything like BestBuy or Fry's electronic shops in your area, or anything like Wallmart, or anything similar?
I build my Inspiron with cash only, so I understand your pain.

Do you live in the big city? If yes, then you must have something!

By choosing your options you are taking chances of ruin all your PC - at best it will destroy motherboard and components, at worst, it may cause fire in the house! Would you be willing to take those chances?
