Not entirely true. I have several of these cases as well, and have been looking at possible upgrades. Gateway made two more microBTX boards that are newer chipsets, with more options, processor-wise, that may be possible to use: look at the mobo for the 4620s, and the E-6610 (Lavacot). The 4620s has better processor options, but you take a hit in memory bandwidth (12.8GB/s vs 6.4GB/s) while the E-6610 is faster (10.6GB/s) with the highest processor options being the Q6600/Q6700 ($$$) and the extreme QX6600/6700. Good luck!
