I purchased two of the Icy Dock adapter to fill the fill the four 5.25 slots in an iStar server case. They are not tray-less, but work well in my server and I won't be pulling them out unless the HDD fails. Trays actually provide a better drive connection to the back-plate. The end result was 6 2tb drives (total 12 tb) in a 4u server case, that can be services from the front without pulling out the server. The iStar case I have has 3 more 5.25 slots and I am contemplation purchasing a 4x3.5 for 3x5.25 Icy dock when I need expansion. The fan on the unit produce average noise levels. For a server that is in another room that's fine, but if you were to use them in a home theater pc (HTPC), I would change them out to a silent fan. The fan is mounted behind the units and are easily remove and have a 3 pin connector. The back-plate has 2 sata power connectors and 3 sata drive connectors, one for each drive. The are really direct connect drive and the unit raid or pooling or multi drive over a single sata connection. So, if you add one of these you need 2 power connectors and 3 sata cables. Icy Dock built a quality product the works well.
TP-LINK TL-SG1024D 10/100/1000Mbps 24-Port Gigabit 13-inch Rackmounta Cons: This did not fit into a normal 6" deep rack (punch down rack) so I had to wall mount it. Does not affect air flow, just looks a bit different. Looking at a 12" deep 6u rack to update my network area. Other Thoughts: Great switch, replaced my 16port TP-Link switch, was plug and play. Is 1.5" deeper than the 10/100 it replaced but still runs quietly, cool and without a fan. I also like that it does not use a "brick" type power adapter. Simplifies the wiring closet and makes use of a standard PC power cord, I used a 90 degree to adapt it to my wiring layout, but a straight plug works as well. Just know that it is 7.1" deep without power cord, so make sure to add that into your rack mount equations.
Needed a switch box bought this one because my other switch had only 6 ports. The price was great for a managed switch and the person that set up my network thought this was a great buy.
I was a little surprised to find the Icy Dock product being offered by Great Offer Stock in my searching for this item but knowing of Great Offer Stock and the price, I decided to buy it from them. I received the Icy Dock within 4-days of ordering it! Open it, inspected it, and installed it, everything worked as designed and described. I will do a little more parts researching on Great Offer Stock from now on!
