deciding between fry's lenovo k330-77275su and best buy's ibuypower bb9371 ? maybe ibuypower 3rd gen. i7 bb982p; i'm worried about ibuypower using 'micro' motherboards; these 2 ibuypower computers both have 1 free pci slot, the lenovo has 2, i think; i might want to upgrade ram to 16gb , and upgrade video card at some future point, i would onlly use this machine for gaming: should i worry about the 'micro' motherboard issue ? lenovo is $950, ibuypower's are $840 and $1000, respectively; thanks i might have to upgrade power supply if i upgraded the video card at some future date; thanks would i be able to make these 3 upgrades to the ibuypower desktops ? thanks
