[98aallen]

hi there guys
im looking to build myself a gaming pc that will be able to handle all the latest games out there without having to noticeably drop the in game graphics specs

i already have an ocz 128gb ssd so will be using that in the new pc. it is currently in my laptop but im sure it will be fine in the pc?
also i dont need software included in the price

all help will be greatly appreciated people, i am new to building a pc for myself, i would like a fairly good spec machine for the price so around about the £400 mark will be my price

thanks in advance

The ssd will work fine in the PC if it's reformatted you can't move your windows or whatever OS over from the laptop like that and if it is windows it's more than likely an OEM version and will refuse to work with another motherboard. you will more than likely need a new OS

This doesn't include OS but you will obviously need one
