Here is what I have so far:
Hardware:
Switch: http://www.pccasegear.com/index.php?main_page=product_info&cPath=200_331&products_id=14362
Server:
CPU: Intel Xeon E3 1245 v2: $325 - Pccase gear
Mobo: Intel DBS1200BTSR: $225 - Scorptech
Ram: Kingston KVR13R9S4/4I 4gb ecc: $69 - Scorptech
PSU: Corsair CX-500w Modular 80+Bronze: $99 - Pccase gear
Storage: WD red 3TBx4: $636 - Pccase gear
OS: Western Digital RE4 500GB: $95 - Pccase gear
WHS: Windows home server 2011 64bit oem: $79 - Ebay
Not sure about which NIC to get for the server. I need one which allows connection teaming so that the speed won't get saturated. (I'm indending this server for 5 people to use simultaneously aswell as potentially using it to host a game server) Also not 100% sure on the OS but I'm leaning towards WHS. I also need a recomendation for a good reliable cable modem. Probably going to need a raid card if the onboard sata isn't good enough. In terms of raid configuration I was thinking raid 5. Also need a decent case for the mATX form factor atleast 5 drive bays.
Router:
CPU/MOBO: ASUS E45M1-M-PRO MB: $145 - Scorptech
Ram: Corsair VS2GB1333D3 2GB: $29 - Scorptech
PSU: Corsair VS350: $49 - Pccase gear
Network Cards: Intel Dual Port Gigabit Server Adapter: $175 - Scorptech
Also looking to get a wireless card but according to this page https://docs.google.com/spreadsheet/ccc?key=0AojFUXcbH0ROdHgwYkFHbkRUdV9hVWljVWl5SXkxbFE&hl=en#gid=0 I need a card with either an Aetheros or Marvell 802.11 N driver.
Also going to pick up a small hard drive and a cheap case to try to keep the cost down.
Cables:
Going to pick up a 100m bulk role of cat 6 cable and make my own lengths using Qain's guide.

Overall I want this network to be reliable, long lasting and not get saturated when multiple people (5+) are using it.
