Pros: These RAM chips are very fast, pretty inexpensive, come with heat-spreaders, and work in my super-finicky Intel DG33FB motherboard. I just installed a second pair for a total of 8GB, and I couldn't be happier.

Cons: The heat-spreaders make pushing the RAM into the slot on the MB a little scary, but by following the included instructions on where to push, I haven't had any problems.

Overall Review: I run 64-bit Linux, so I don't have any issues with 4+ GB of RAM, but remember that 32-bit Linux will address more than 4GB, but will only allow each individual program to use 3GB. 32-bit Windows will (AFAIK) only allow 3-4 GB to be used total, so if you want to have more, you have to choose 64-bit Windows or Linux.

Pros: Inexpensive and works fine with jumbo frames. I used one of these to connect a database server and a web servers in a DC. They were under pretty heavy load, but the switch never had any trouble. Also had one between the servers and the uplink to the DC, which also worked fine. The two servers used 1GB connections and the DC's uplink was 100MB.

Cons: Not a metal enclosure.

Overall Review: For the money, I would totally recommend these.

Pros: This unit has very simple instructions for installing, including a CD that will (I assume, since I immediately threw it away) configure your computer for you automatically, which is probably a boon for less experienced users. I immediately installed OpenWRT (it is only supported by the Kamikaze release), which worked great once I did "ipkg install kmod-brcm-wl-mimo" for the wireless driver. I haven't tested N speeds. DD-WRT works great too.

Cons: The antennas are integrated, which means no replacing them without opening up the case and grabbing a soldering iron. The support in OpenWRT for this router is very new, so people looking for a good OpenWRT box should be aware that it will require some tinkering to get working. I experienced some instability when using WPA, but unencrypted and WEP worked fine.

Overall Review: This is a good price for an N-capable router that runs OpenWRT, assuming you don't mind getting your hands dirty with the configuration. There is supposedly better support in trunk, so if you're up to compiling a version yourself, you might have a better experience. DD-WRT works great out of the box.
