Pros: it auto clocked the core I7 6700 to 4GHZ . dual ethernet ports work great. sata express ports , i had issues with, see other thoughts board posts fast, even with fast boot off . my aging sabertooth could take up to a minute to post... bios relatively easy to navigate, lots of features (some are not supported by the I7 6700 non-k model). paired with a regular ssd, debian 8 goes from the grub logon to the KDE logon manager in about 1 sec, another 3 to a full KDE5 plasma desktop... this combo smokes. a full debian server boots in under 5 seconds .

Cons: see other thoughts ** update /11/26/2016 board started to get into a boot loop before BIOS with code 29 (or 62). unplugging from wall and hitting the power button will *usually* get it to boot into debian (the only os on it, and its being used as a server) . once booted it will stay up for weeks (current uptime 5 days 12 hrs and 55 minutes) until a reboot is needed (due to updated kernel or similar) . this will seemingly show the cpu, ram (tested with linux memtester utility), and psu (seasonic gold 650W) is ok . unplugged all usb devices ,same results. boot loop gets to code 29, hangs for a few seconds , then restarts. no chance of entering bios (unless i unplug as above). ** at this point i cant recommend this board due to this issue. changed from 5 eggs to 2. /*edit*/ and back to 5 eggs. turns out a faulty usb hub was the problem, as unplugging everything else including hard drives and expansion cards proved fruitless. unplugged the hub (no kb/mouse) and bam booted fine. plug kb/mouse directly into board (had them plugged into the hub as an extension) and still booted fine. hooked up everything except hub, boots fine. further investigation reveals that this board has random problems with usb devices, even keyboards and mice. so unplug everything, drives,expansion cards (use onboard video) all external connections except power and try to boot the board. lesson learned.

Overall Review: i paired this board with a coolermaster N400 case. the board bolted in fine, but the case has a lip right on the side between the drive cage and the sata express ports. getting std sata cables in was a tight fit, but i got it done. not sure that sata express cables would fit on the 2 sata express ports closest to the motherboard, with this case. this isnt the boards (or the cases) fault, just a random unforeseen issue.

Pros: look nice, lat ones i bought are great

Cons: the speakers have a internal short which causes them to lose power ,or become noisy when used. moving the wires around a bit changes things, sometimes it works , sometimes you get a bunch of noise, sometimes you lose power.

Overall Review: might just be my set, but i dont recommend these refurbs. buy them new.

Pros: fit everything into it;dvd drive, 3.5" hard drive, and the minitix am1 board.

Cons: psu died after a year. it intermittently loses the 5v rail. this means usb devices get no power, also causes bluescreens on windows. also while testing it got hot. almost to hot to handle.

Pros: paired with a asrock server board and a g4400t processor. stays cool , works well.

Cons: it doesnt get hot enough to cook bacon (but my dell 2950 memory does)

Overall Review: recommend as it just works.

Pros: added a g4400T and 4GB ram, perfect for a pfsense router. dual intel nics are a plus .

Cons: none at this point

Overall Review: put it in a 2U chassis and rack mounted it. perfect for my needs.

Pros: works as advertised, even with a bad (wont charge) iphone battery

Cons: didnt come with bacon
