I don't know what your price range is, but I do know that build up above could use some help. Let's see what we can do here.
Also please post a budget, and if that budget includes an O/S (Operating system/Windows). If your on a budget, remember to "shop around"...don't let newegg be your only source for hardware or your going to cheat yourself out of $$$ not to mention your going to end up with a crappier build than what you could have. Ok let's try this.....
1) You chose a nice looking case, but when your on a budget and the expense of the case takes away from the rest of your buid....well look for an alternative case that still looks decent, is inexpensive, and does a decent job ..sans cooling/ventilation/air flow, room, etc...
2) That 850w psu you have is great if your going to run something like 2 x gtx 285's in SLI...but your not. Try out this 500w down below. It's more than enough to push your rig including vid card.
3) The mobo and cpu combo you found is a great deal and all that, but it's over kill if you don't plan on over clocking with that board, and your not running a high end vid card. This board and cpu down below will allow you to push that E7400 up to 3.5GHz @ 1333 fsb (10.5 x 333) with a decent after market heat sink and thermal compound. But as it is, that cpu will do just fine for what you want it for, and it won't bottle neck your vid card.
4) Vid card: This gts 250 is twice the vid card you chose, and will allow you to play better games and not get hosed on the fps.
5) Memory...this G.Skill down below is what we call "solid memory". It's a rarity if someone ever gets a bad stick of this, and it's always compatible with just about every mobo out there. Good cheap solid memory that does what it's suppose to.
6) dvd/cd burner...you chose an EIDE burner...never ever choose EIDE anything. Always get the SATA due to airflow, ease of installation, etc....
7) Monitor...This monitor down below is a 19" wide screen, but it has a native resolution of 1680 x 1050...up from the standard 1440 x 900 for 19" wide screens.
8) I'm not sure if you have an O/S, so I put the link for Vista 64 Home Premium oem on this post.
