As per title.
e.g. - If you want an affordable Mtk Wireless AC device, there is nothing prebuilt, but they make http://routerboard.com/RB911G-5HPacD and http://routerboard.com/RB922UAGS-5HPacD - the latter of which has better specs than anything up to and including a CRS109 (unless you need multiple ethernet ports)
And if you want a multiport router, the http://routerboard.com/RB850Gx2 seems significantly advanced over the prebuilt offerings.
I understand for those comfortable with assembling their own solution this is not a problem, but some of us like the security (and warranty benefits) of buying a prepackaged solution. So I'm just curious why it seems the preassembled options seem to lag a generation or two behind the board-only options?
Cheers.
