Which of those "needs" 10Gb though? the cameras won't max a 1gb link, nor would a web server. The only that may is the NAS and at that I'd bet you'll be HDD limited before you are network limited. What needs to transfer at 10Gb to what else? If it was me, I'd say stuff it and go with a CRS328 which has everything you want in one (In fact that's what I did).
