Pros: Highest CPM 120mm fan I could find (Max 110.03 CFM) Adjustable fan speed with "floppy drive" control faceplate, so you can turn down the fan when not doing CPU intensive stuff. For me, this was the perfect fan to use with my Thermalright SI-128 CPU heat sink.

Cons: Not a negative for me, while this fan is quiet, (sounds like a normal PC, NO JET ENGINE SOUND) it is not absolutely silent. This might be important for HTPC builders, where you might need absolute silence. Very Quiet, but not dead silent.

Overall Review: Perfect fan for my Thermalright SI-128 HSF. Could not be happier with this fan. I HAD an 80mm fan on my last HSF, that went up to 5000 rpm, and it sounded very loud, whereas the Silverstone fan is much quieter, while still providing a lot of air flow.

Pros: Seems well made, about as sturdy as any other component type of product (motherboard, video card, etc). After setting and confirming that the DVD Burner jumper was set to MASTER (there is master, slave, and cable select) the BIOS of my Dell Precision 380 reported seeing the DVD Burner YEA! (Tried both a BenQ 1640 and a Plextor 760a), but . . . (see cons below)

Cons: Windows XP Pro SP3 DID NOT recognise the DVD Burner. I played with this for about 3-4 hours, and while the BIOS always reported seeing the DVD Burner, windows XP SP3 would not recognise the drive. I tried both: CONTROL PANEL-SYSTEM-HARDWARE-DEVICE MANAGER=ACTION - SCAN FOR HARDWARE CHANGES and CONTROL PANEL-ADD HARDWARE (USED WIZARD) and CONTROL PANEL-ADMINISTRATIVE TOOLS-COMPUTER MANAGEMENT-DISK MANAGEMENT All with no luck

Overall Review: I didnt send this back, it would cost more in shipping that it is worth. I do have a feeling that it was my "specific pc" (maybe the IDE and SATA chipset??) that was the issue? I dont know, maybe I will have a use for it down the road. I put one in my Dad's PC to run his Hard Drive, and it works just fine. Lights flashed on and off of the DVD Burners during the POST test, I could open and shut the doors, everything seemed to work except for Windows recognising the Burner. I have two fantastic IDE DVD Burners, and wanted them to both have their own channel, that is why I bought this. What I should have done, was to spend a little extra, buy a SATA DVD Burner instead. I hate to give this thing a "very poor" rating, but for me, it did not work, and this thing is either a "1" or a "5" type of product. I wish the description would be clearer as to weather or not it supports DVD Burners.

Pros: I have this connected to a Dell Precision T3500 and a Dell OptiPlex 790. I use it daily, and it works very well. Very happy with this device.

Cons: Every once in a while, I have to re-boot one of the computers, because it does not re-connect. I would say, maybe once a month or so, maybe even less. Also, it takes 5-10 seconds to re-sync the mouse and keyboard, and if you start typing-mouseing too soon, it will "studder" then "catch up". Not a big deal.

Overall Review: I wish there was a command line interface for the software, sometimes I forget to switch, and I often remote into my Precision T3500. If I forget to switch to the T3500 before leaving for the day, the display is all messed up, when I remote into the computer. If I had a command line option, I would write a "scheduled task" to switch to computer 1 every night.

Pros: Do not own yet, but I do own the SP-BS21-LR, and I can tell you that my experience is that they need some time to "break in". My 21's sounded very boring, almost like a AM radio at first, then I played them for 80 hours or so, then gave them another critical listen, and they sounded very nice!

Cons: Have to break in.

Pros: Not much to say, other than it work as expected in three Dell OptiPlex 780's

Cons: None

Pros: I have two of these keyboards, both for KVM switches that need PS/2 connections. They both work flawlessly. Keyboard is a quiet membrane type keyboard (did not take it apart), and while I prefer a click/tactile keyboard, this keyboard is very acceptable. Very lightweight.

Cons: Not really a "negative", but as the keyboard is soo lightweight, I had to use extra gel wrist pads to secure it firmly.

Overall Review: Again, very happy for this PS/2 Keyboard.
