Pros: Great 890FX chipset. Has IDE, has DUAL 16X PCIe plus PCIe 4 and they don't share bandwidth, has PCI x 2 (in addition to the PCIe) Works with Linux (with a few non-critical issues, see below). SATA hotswap works great! Network, SATA, and USB are fast and reliable. Board looks to be well designed, all passive cooling, everything well labeled. BIOS has more settings than you can shake a stick at. USB 3 for someday. SATA 6.0 (which is a waste, but whatever). Still has a serial port (yay!) although on a non-included bracket. Dual PS/2- handy! Had no trouble installing, everything fit fine. Neat POWERED E-SATA connector on back. I think it is a reasonable price for features offered.

Cons: Had a problem that if I turned on the IOMMU in the BIOS, it prevented Nvidia drivers from working and IDE DVD drive to revert to slowest possible performance. Took a while to eventually find it and turn it off. I don't really need the IOMMU right now (really only used for virtual machines) and assume it will be addressed later. Audio drivers for this chipset in Linux are weak (no optical, lame mixer) so I reverted to my old Soundblaster Live PCI for now. Linux doesn't like the new version of Cool n' Quiet yet, so I had to turn it off (otherwise, CPU reverts to REALLY slow, full-time!) but sure this will be fixed soon (not a big whoop, it jumps all 6 cores to 3.6Ghz instead, fine with me!). The BIOS section in manual is typical- doesn't explain much. Asus "Express Gate", the [supposedly] "instant-on" mini Linux is STUPID, it is not on the motherboard, it is loaded (with MS-Windows only, of course) on a hard drive! FAIL...non feature. No floppy, but I guess I don't care

Overall Review: This is an update to the non USB3 board with the same model number. It is otherwise identical. Knew it was coming out, so I waited for it :) Mated this board with 8GB of G.SKILL F3-12800CL7D-4GBRH, and a Phenom II X6 1090T Black, and an older fanless 16x Asus Nvidia card. Has been running 24x7 for almost a month and so far so good. Don't waste time with the stupid BIOS RAID, just use Linux software RAID instead- which will perform better and be much more flexible. Replaced an old pre-AM Asus motherboard I was very happy with, so I decided to go with Asus again. I think I made the right choice.

Pros: The *CONCEPT* is exactly what I was looking for- dual slot 2.5", thermostatically controlled fan, usb. I already had an older unit (BT-B260U3) before ordering three of these (BT-B260U3F)

Cons: TWO of the three units I ordered were defective right out of the box. One unit had no USB response at all. The second unit had a broken eject mechanism on one of the two slots. The third unit works, but the eject mechanism is suspect, as if it is going to break soon. I have no confidence the third unit will survive.

Overall Review: I decided to keep one as a backup for a different model I bought earlier that works great (the BT-M260U3). I would have bought another of those, but they were discontinued and I had to buy the more expensive "F" model, even though I did not want firewire or ESATA. Newegg's *EXCELLENT* customer service immediately understood my issues and not only issued a refund so I could buy something different, but waved the restocking fees and return shipping costs! Although I am upset about the products, I can't possibly be more pleased with how NewEgg handled it!

Pros: This is the smallest of an affordable 32GB flash drive I could find. It is truly tiny. The metal cover can be removed easily, leaving a black nub that is only 15mm long and 5mm thick! Formatted FAT32 with one primary partition and no crapware or other junk.

Cons: Not a speed demon. Has no activity light. Has holes for a lanyard, but no lanyard.

Overall Review: Immediately repartitioned all four I bought and formatted with ext4. Works perfectly with Linux. Tested sequential writing under Linux (using simple 1GB copies: sync ; date ; cp FILE /mnt/disk ; sync ; date ) at 10MB/s on one machine and 8.8MB/s on another.

Pros: Works fine in Linux (RHEL 6.1) Aluminum top/bottom/sides. Thermostatically controlled fan (a feature they don't list). Attractive. Weighty enough to stay put (once you add feet). Dual slot! Slots separated enough to provide good ventilation. Included USB 3 cable (although it is non-case matching blue). USB 2 compatible. Drive activity light (reuses power lights on each slot). Works fine without RAID. Very reasonably priced. Well packaged, nice box. Compact power supply. Power switch. Had no trouble inserting or removing drives.

Cons: No rubber feet included (easily fixed/obtained). No "drive inserted" indicators. Plastic front and back (but that is not unusual). Not lockable (not a big deal). Instructions are pretty skimpy.

Overall Review: When power is applied, the single blue LED comes on for each tray, whether there is a drive in it or not. During activity, the light blinks off. Would much rather have had separate master power LED, a drive inserted lights, and activity lights. I did not test RAID capability (since that is not what I plan to use it for). I benchmarked (bonnie++) Seagate ST9750420AS 750GB drive in the slot connected to RHEL with USB 2 and got 28MB/s write and 47MB/s read. The read speed is right at the max USB 2.0 speed. The same drive, connected to the same machine but directly through SATA yeilds 42MB/s write and 165MB/s read. If the controller in the Bytecc can't max the bus on USB 2 for writing, I am not sure what the point of connecting it USB 3 would be. This could be a major strike against the unit for some people. It could be a limitation of my server's USB chipset (HP ML350G6). But for my application (replacing a tape backup system for a server), it doesn't matter much.

Pros: So far so good- works perfectly (1 month 24x7) HUGE quiet fan. Detachable extra power leads. Had all the power leads I need, and tons of room for growth. Power efficient (also tested that with a Kill-a-Watt).

Cons: Some of the power leads I do NOT need are NOT detachable. So it is not as clean and modular as I would have liked. I wish it had a fan controller built-in for external fans, like my TruPower one did. The "manual", such that it is, is pretty spartan.

Overall Review: This replaces a 5-year old 430Watt Antec TruPower 2.0 power supply that I never had ANY problems with. Needed more watts for a new MB/CPU/mem.

Pros: Fast Great value Nice heatsink Motherboard and Linux both like it Good power profile

Cons: Slight problem that Linux doesn't yet like the new AMD Cool n' Quiet (AKA Turbo CORE). If it is turned on, then all cores drop to something like 1.4Ghz full time. No big whoop, just turn it off and they all run at 3.6Ghz full time. This is supposedly already corrected in newer kernels.

Overall Review: Installed in an ASUS M4A89TD PRO/USB3 AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard with 8GB of G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) memory. When testing/benchmarking it, it was difficult to keep all the cores busy :) It is silly to have this many cores in a home desktop. But it didn't cost much more, so what the hell. Now I can see LOTS of "cpu's" idle in top :) This replaces a older Athlon 64 x2 CPU (diff MB) and I was very happy with that chip's performance, reliability, and value... so it was only natural to want another AMD system.
