Hello! I've been reading the boards and eyeing building my own build to run Sophos' awesome home UTM - finally have the funds and time to do it.
I've been reading the stickies and reviewing past posts, but still want affirmation I'm on the right track.
I currently get 30 up & down, with 4 users, but want headroom for 50/50 and 6 users down the line.
My proposed build has the headroom in mind (opted for the i3, though probably a little more than I need):
i3 4160
GA H87N MoBo (cheapest mITX board I could find with an Intel NIC)
2x4GB G.Skill RAM (8gb total)
160GB 3.5inch WD Blue 7200 drive
Intel EXPI9301CTBLK 10/100/1000 Mbps PCI-Express x1 NIC
I saw Barry's posts about the great form factor in a Node 304, but I have a footprint that I want to actually stack on top of, so using a Cooler Master 915 - got space for a full ATX PSU. Gonna use a Corsair 450 CSM - overkill, but its the cheapest, quality modular PSU I could find, and at 30 bucks it seemed worth it to buy a quality PSU I could probably reuse. And nice that's its Gold efficient.
So - does everything look okay? Is having one Intel NIC in the MoBo and another in the card okay for a simple WAN and LAN port (LAN port would also be used for management)? or do I need to buy an Intel NIC with 2 ports, and cannot use the MoBo's port? Do I need a DMZ port? This MoBo actually has 2 LAN ports, but one is an Atheros which I know from reading the board won't work, so I was just going to disable it in the BIOS.
I also wanted to make sure my proposing network topology made sense: I plan to replace my existing netgear router with the UTM (so optical modem -> UTM -> my network), and then put my netgear router into bridge/wireless AP mode behind the UTM (to use its other three wired ports, and the wireless). I also have an 8 port switch down the line.
Look okay?
