I am going to be building a new computer soon, it'll be packed into a Thermaltake Lanbox, I've lined up some components after looking around. Are there any major problems, it should all fit together and work.. I'm looking at gaming with this machine after some minor overclocking, I'm still undecided on the graphics card. I'm am also starting to question the processor and powersupply..

For a pc in a lanbox, you did pretty well, it looks like you thought through the low heat parts. A "E" series processor is pretty ideal, especially with overclocking. As far as a GPU goes you need somthing cool, powercolour are usually pretty good with stock cooling. And for a PSU, for my lanbox, i got the one with the largest fan possible to aid in bringing in cool air, just a thought. I would go a 500 or 550 for that build, mostly to keep eficiency high and heat low.
