Had some trouble installing EVGA 1080 graphics cards due to power supply box location, but removing the cross bar enabled me to get both hands in to line it up. A few glitches getting the MSI laptop to recognise it but once the kinks worked out the laptop detects the 1080 card when Omen connected. Even though it has plenty of USB ports they struggle with too many attachments (they couldn't handle Oculus Rift with 3 sensors, luckily I discovered Oculus sees the 1080 card even when attached to laptop USBs.) Haven't tried a hard drive yet. For the price can't complain.
