Pros: - Low power usage - Small, neat looking unit - Allows use of armel Debian port, so it becomes a general purpose server - Serial port pinouts on motherboard, allowing serial interface to be attached

Cons: - Limited HD support (you have to do your homework first) - Fan is somewhat loud, even at low settings - Blinding blue leds - SoC's CPU lacks an FPU, so using Java applications like CrashPlan probably not practical - Use of serial interface requires hacking a serial interface into the case (doable, but not everyone's cup of tea)

Overall Review: Bought this to use as a low power Linux home server, so I immediately installed Debian on it and have no comments about the stock firmware and software features of QNAP OS - this is just a hardware review. Overall, considering the price, I'm quite happy with it. It uses very little power (the main reason to use something like this versus an old PC), has two 3.5" SATA slots, Gigabit ethernet, and runs Debian Linux... yay! It's not perfect though. It is picky about the drive models it supports - I didn't take this seriously when I ordered it, and found that the WD Caviar Green drives I was intending to put in it were simply not recognized. A replacement drive selected off the supported drives list sorted this out, but it was an added expense, so check that list first... Secondly, it's not silent. It has a small fan that makes a noticeable hum even at a fairly low setting. I now have it in the basement, so it's not an issue, but something to consider if you are in a small apartment. The blue LEDs on the front are blinding - I ended up dabbing a bit of white paint onto them while the case was off to bring them down to a reasonable level of brightness... Finally (and this is not really a complaint, considering the cost) but the CPU is not very powerful and lacks a floating point unit. This means that you won't want to use it for anything that requires much processing power, and the lack of FPU means some useful applications like Crashplan (which uses Java) will be poorly performing if they work at all. So far this as been the one application I wish I could run on it but which I probably never will be able to. But, overall, considering the price and the nice neat package, I'd give it 3.5/5, which rounds up to 4 ;)

Pros: Very, very quiet. Pretty much silent unless you stick your ear right up to it in a very quiet room.

Cons: Minimal airflow. It is spinning but barely makes a strip of tissue paper move. The airflow isn't detectable on your skin.

Overall Review: Replaced the stock drive in an MSI Atom 'barebones' desktop that I use as a server. The whole thing has been running 24/7 for over a year now with two 1TB WD Green drivers, but the fan is not doing much for cooling.. It just doesn't move enough air. I think the fact that the CPUs and drives are low power types means that i've gotten away with it, but I almost wonder if no fan and just convection would be the same. But hey, it's silent and the system hasn't had an issue, so I'll give it 3 stars.

Pros: Cheap, with good driver support. Works out of the box on Debian Linux, and a choice of proprietary and open source drivers are available for Mac OS X. Not sure about Windows but I'd guess it works too since the PL2303 chip is so common.

Cons: No documentation! Trial and error needed to determine which wire is which.

Overall Review: Overall this device is fine, but it was frustrating that no information was given on which wire corresponded to Gnd/Tx/Rx/Vcc. There are no color standards for this, and even when I cracked open the case to see the PCB, the printed labels were not correct! Eventually I figured it out (but not before spending money on a different one thinking this one was broken!) Ground: Black Rx: Green Tx: White Vcc: Red

Pros: Very quiet.

Cons: Very low airflow, questionable durability

Overall Review: Installed this fan in a small server, running 24/7, in early 2009. This summer (2.5 years later) it began to make noise - it was still running, but the noise indicated that the 'fluid dynamic bearing' was failing. Replaced the fan with a more standard unit. Overall, a bit disappointing with the tiny airflow and relatively short life.

Pros: Inexpensive, sturdy metal construction, compact and fanless, looks good.

Cons: None

Overall Review: I've had this switch for just about a year now, and it's been just fine. I have a mixed 100/1000 BaseT network with a Linksys WRT-54GL running Tomato Firmware, so I use this switch to provide a Gigabit link between my file/media server and devices that can utilize Gigabit.. for the others (network printer, cable modem) i use the switch built into the Linksys, for some maybe imaginary power savings (since this switch cuts power to unused ports, and those devices would not benefit from Gigabit). Anyhow, no complaints - it works as it should. Have not tried Jumbo frames as my network, as mentioned, is a mixed one.

Pros: Very quiet, run cool, no problems to speak of.

Cons: None so far (two drives, 8 months continuous use in as server)

Overall Review: I installed two of these in a home file/web server about 8 months ago. The server is a slim Atom based Hackintosh, with pretty poor cooling, and it's only designed for one HD - the second was stuffed into the optical drive bay. Despite this, they've been running 24/7 for 8 months without a hiccup. I bought them for their low noise and heat, and they've done the job beautifully so far. They aren't slow either! Highly recommended
