Redoing my whole home network infrastructure towards a business one for testing...

Hello......

Currently my network is composed of 3 Windows PCs domain capable and 1 nondomain capable (will be upgraded to domain capable). There are other devices (smartphones, TVs, etc) in the network as well.....

Connectivy of these devices is held by one DD-WRT router (with a ISP standalone modem) and another DD-WRT simply extending the wireless range.

Basically since Im going to go towards Cisco in the future, I want to restructure my entire network.

My idea is this:

2 new "PC" in this structure. I call them "PC" because of the following:

1 will have 2 NICs running pfSense, which will essentially act as my router (and a couple of things also, see below). One NIC goes from my broadband modem and the other NIC to a yet to be determained switch.
Another PC will be a domain controller

Next:

A L3 switch where I can configure it to the level almost of a router.

So my questions are:
What do I do about wireless? Should I get a dedicated device that can really extend wireless thruout my house (3 stories and it will be located in the attic)
The two new PCs should be more than enough with low priced right? For example, two of these:

http://www.newegg.com/Product/Product.aspx?Item=N82E16883155554

Should be more than enough, right? Like I said 4 PCs are going to be connected to this domain.
This network, for future proofing (and learning), I wish to be mixed IPv4 and IPv6. Means each PC will have a local IPv6 address (even if unneccesary) and a local IPv4. They should be also ready to access IPv6 sites (thru tunnels or otherwise).
The pfSense will act as I said a router but should be my firewall and also a VPN server. What kind is yet to be determained.

As you can see, my network is complex but also something that I should see in the future in business networks. If someone could help me out with tips and orientations, thank you very much.
 
If you are going with such high end networking equipment then why not purchase a managed cisco or aruba wireless system? It would be way overkill for your use (but your setup is already overkill), but it would be a good learning experience, and you could walk into a ton of jobs if you know how to run and manage said systems.

For the PC, if you need to purchase new then those little Dell units ought to be OK for most things, but you can probably get much more powerful used systems for less or free if you poke around the web a bit.

As for orientations and such, I am far from an expert, but just from practical expierence I can tell you this: Keep all wireless devices away from needless wires and power lines. upgrade old noisy fluorescent light bulbs to newer balasts or other 'low noise' lighting tech (if you have any). Put either a single router dead center in the home, or else have 2 routers on opposite ends of a large home. Prevent your antennas from being parallel to eachother, setting them at opposing 45* angles is typically good for preventing odd issues of self-interference and dead spots.
And lastly, having a newer home that does not have things like brick walls or metal piping can go a long way to getting better range. I have a 60 year old home which has perfect 2.4 and 5GHz reception anywhere indoors... but you walk outside and you get absolutely nothing. Brick just kills reception, and if you have an interior brick wall (or a needlessly complicated electrical or metal piping system) in your home it can cause all sorts of issues. Wood, drywall, and pex tubing are much less troublesome.

Well I am on a "as small as possible" budget as if I wasnt I would completely go Cisco and/or wire the entire house to ommit wireless.
 

Wired is super cheap if you are doing it yourself. Its like $75 for a 1000 foot box of basic ethernet cable, $10-20 for a crimper, $5 for a box of heads, and then a few bucks per wall outlet. Not exactly 'free' but way more reliable than wireless for about the price of a single wireless router.

If you looking to learn cisco check out GNS3. It will give you 1000% more experience and exposure than a 4 node home network. Which isn't realistically anything like a business environment.

Toss in a 4 port nic on your most beastly machine. Boot up 20 vm's and push traffic through to virtualized remote offices. Buy 2 asa's and use a breakout switch to connect to your virtualized 20 hop network. Practice setting up site-site vpn's. Then move into dmvpn's and high availability/ redudant designs. This should keep you busy for a year or two.
