Hi guys was wondering whats the deal with the r5, all I see on here is r2, r3, r4? Does anyone have this model? I have the m17x r5, bios version A07, which is the latest. I was wondering is there an unlocked bios for this? I wanted to do some upgrades like get 2x 1tb samsung evo ssds put them in raid 0 - does anyone think this is a bad idea? I saw upgrademonkey has the geforce 880m 8gb I was thinking I might get this, I already have an 780m? Am I being stupid I ideally also want to upgrade the msata(but seems dangerious opening) and the blu ray to a blu ray writer drive but nto sure which one I can get? Any suggestions?
