Pros: Solid construction and a great value at its current price in the mid eighties. Lots of room to work. Includes plenty of drive brackets, CPU cooler brackets, and screws.

Cons: The motherboard standoffs are taller than you might expect: the motherboard sits about an inch above the floor of the case. Consequently, CPU coolers with a height of 160 mm will not fit. (Voice of experience.) Minus one egg. My second choice CPU cooler was 140 mm tall and fit well. I can't be sure whether a 150 mm tall CPU cooler would fit or not.

Overall Review: Works great with iStarUSA model IS-20 rack rails. Also, if you're wondering what's the difference between this case, model RPC-450B, and Norco's other model RPC-450 for a few dollars less, look carefully at the photos. The top and sides of this case are painted black.

Pros: The hub has a convenient shape and size. The straight stack of ports in the back is nice. Haven't noticed any data corruption or unbearably slow speeds. They've lasted two years so far.

Cons: After about six months of use, two of these hubs started acting finicky when I would bring the attached computer out of standby. About 20% of the time, one of them would require a hard reset by removing then reinserting the power and USB cables. Regular boots worked fine, it was just standby that caused me problems. Two years of this is enough -- I finally broke down and bought a more expensive/more reliable hub.

Overall Review: Why do *so many* of the cheap hubs fail in the same way: random disconnects cured by cycling power?

Pros: Shows up as a "CSR Bluetooth Radio" in Device Manager on Windows 7. Windows 7 comes with drivers for some basic functionality like keyboards, mice, and file transfers, no additional install needed. The bundled CD also includes a copy of the Toshiba Bluetooth stack software from 2009 (version 7.x). By installing the Toshiba software (and disabling Windows 7's native Bluetooth support), you gain support for a dozen more Bluetooth profiles like headsets and handsfree telephony.

Cons: Not suitable for use with a Bluetooth headset for speech recognition. The Windows 7 stock driver for a "CSR Bluetooth Radio" does not support any audio functionality. Thus I turned to the Toshiba Bluetooth stack software. Audio quality through the Toshiba stack's headset profile and handsfree telephony profile was poor bordering on unacceptable. Lots of hissing and digital artifacts. My speech recognition software went nuts. I'm sending it back for a refund!

Overall Review: The bundled Toshiba software is a little dated (from 2009). Newer versions are available for download online... but look carefully. All of the copies available online for download are 30-day trialware. A full new license for the Toshiba Bluetooth stack costs $30. There's nothing useful on Kensington's web site. As for me, I chose to stick with the Toshiba software on the bundled CD because it was licensed already and did not require activation.

Pros: Good price at less than fifteen. Compact size. There is a WHQL driver for Windows 7 available out on Windows Update, so on Windows 7 installation is painless and wireless zero config (WZC) works properly.

Cons: Zonet's drivers for Windows XP are subpar, as others have noted. They are tightly bound to Zonet's Wifi "management" program which seems intended to replace Windows' wireless zero config (WZC). Unfortunately, like so many other kooky OEM applets, the "management" program is buggy. It fails to connect to ad-hoc networks, it mangles several WPA security parameters, and the "softAP" feature crumps intermittently. I spent a few hours trying to tease the core driver files out of Zonet's installer, with the hope of bypassing Zonet's "management" program, but I gave up. Also, Zonet's driver is not WHQL certified. Bad form. The driver package posted on Zonet's web site as of this writing is a couple years old and no fresher than the drivers included on a CD-ROM in the box. These drivers are so poor I was ready to return the product, but then I discovered...

Overall Review: ... the chip inside this dongle is model RT2870 from a company called RaLink. Luckily, RaLink makes good drivers! Zonet is just failing to pass them along to us, the end users. Surf to http://www.ralinktech.com/support.php , find the right chip, and download away. The drivers there were published in December 2009 and purportedly cover Windows 2000, XP 32 and 64, Vista 32 and 64, and Seven 32 and 64. They are WHQL certified and play nicely with Windows' wireless zero config (WZC). The install program has an option to install a driver and management utility, or just a driver. I recommend the latter. Thanks to the RaLink driver I've been enjoying good performance so far. RaLink spared my dongle from an early demise.

Pros: Works about as well as you'd expect from a pair of cheap rack rails. Beats the pants off of pulling the whole chassis off the rack every time you want to service it.

Cons: The glide isn't too smooth and there's a fair amount of wobble. Also, as another reviewer noted, the plastic locking tabs feel weak and might break under heavy use.

Overall Review: Attached to my Norco model 450 case just fine. Seems to be designed for a square-hole rack as other have noted. You insert a screw from the front side of your rack, through a hole in your rack, into one of the rail's brackets. Nonetheless, these rails worked well enough in my round-hole rack. The holes in my rack are sized for #10-32 screws. These rails use #8 machine screws. The screws are small enough that they slipped right through my rack's screw holes and so attached to the rail brackets as intended. It's always nice to avoid breaking out the drill. No harm, no foul.

Pros: Reasonable performance. I put three of these drives in a RAID 5 array on a 3ware 9650 controller. HDtune results for the array: Read 130-230 MByte/s Write 100-160 MByte/s Random seek 77 IOP/s Sequential read outer 206.855 MByte/s Sequential read middle 191.884 MByte/s Sequential read inner 115.204 MByte/s Burst rate 135.344 MByte/s

Cons: They run a little hot. Pushing 45 C under heavy load while sitting out on the bench.

Overall Review: I bought my drives on sale at a retail electronics store for one hundred twenty nine bills each. You know when you walk into a McDonald's, and order a Big Mac, and they ask if you want ___ with that? Well that's where I found my drives. Maybe you'd like to wait until Newegg puts these guys on sale.
