solid product bad engineering on CPU bracket . when purchase I think this would be quite easy to install since I have over 20 year experience . this be not so the biggest problem be with the CPU bracket be poorly design . it consist of loosely install the bracket and then twist the CPU heat sink into position then tighten the bracket down . do not sound very hard but actually to accomplish this I have to install the heatsink on the motherboard before install the motherboard , and work with three large piece the motherboard , video card and the radiator install all at once prove to be a challenge without break something .
