I recently built this machine for a local business that is currently using an awful Mac Mini, its mostly going to be used by the secretary as a general use office computer. I chose the AMD A4-6300 because of its cost/performance ratio. For the price the processor is great! MOBO was great as well, MSI makes good stuff and for a $60 motherboard its a killer deal. The ram was chosen just for the good price and good reviews on NewEgg. The Barracuda was an obvious choice as it tends to stay the favorite of most builders on a budget, although I have noticed a high pitched whistle ever so often and I'm hoping its nothing serious and it will go away when it gets broke in, but I will keep an eye on it. As for the case I've always wanted to try this case from Rosewill and so far it has impressed me. It came with a PSU that seems to be solid but you never know with these free power supplies but we will see.
Let me know what ya think! THANKS!
