DrWho, I was originally looking into doing a budget build using the DIY combos on Newegg, but I decided not to.
Logisis (however it is spelled) is apparently one of the worst PSU makers. It is safer in the long run to choose parts yourself over a bundle (Unless the bundle includes decent parts).
You can barely buy a 1TB harddrive for that price lately. Don't get me wrong, this is a piece of junk. But it's a piece of junk that'll do everything you need it to do for a few years before dying a horrible death. Still, tough to beat the price.
For a budget of $300 , with monitor included is a tight one. Based on them here's a build that goes overbudget . You would like to take a look at it.
It will be really great if you could salvage a HDD from somewhere as it would allow you to get some better components.
