First Build

Hello, I'm new to Tom's Hardware forums, though, I've been coming to the site for quite a while. I've been interested in build a PC, I don't have much experience in some aspects such as brands when it comes to motherboards and other parts. Well, I'm planning to building a PC for home use. Right now, I have 2 lists, but I'm not sure if I should change something.

Here's what I have:

AMD build: http://secure.newegg.com/WishList/ [...] r=13994407

Intel Build: http://secure.newegg.com/WishList/ [...] r=13994467

I'm trying to keep it in the $300 range(Shipping and tax not included).
I have a monitor already, so that's no problem.
I'm looking for suggestions, and opinions on what I have right now. Also, maybe your experience with any of the parts on the list. Thanks in advance

PS: I'm hoping to get a build I could upgrade in the future, such as add a GPU or more RAM.

Both are pretty well thought out rigs. I might change the case/PSU combo to what flyin15 suggested or at least this Rosewill rig which uses one of their newer designed 450w PSUs

For the AMD build i'd try to squeeze in the athlon64 x2 7750 and for the Intel build try to squeeze in the E5200
