Pros: Well constructed, heavy duty case. I like the hard drive cage and a hot swap cage might be a great upgrade.

Cons: The posts for mounting the motherboard are fixed (as far as I can tell) and didn't line up perfectly with my motherboard (SuperMicro X9DRL-3f). I just dremeled off the one I didn't need (it would've been in contact with the back of the motherboard in a very bad way). Could also use more airflow in this case...

Pros: It was cheap.

Cons: Problems from day one with this board. It would only post half the time, OS would constantly freeze up. Memtest failed like crazy and Kingston replaced my 8x KVR1333D3D4R9S/8G (listed as compatible) with 8x KVR13LR9D4/8HC which they say is "more compatible." This fixed my memtest failures. Computer still fails to boot up the majority of the time. Sent in for RMA and all they said was "it works." It was a super drawn out process to deal with Supermicro support so there's no way to just return this and try a different motherboard. I give them the codes where the motherboard hangs up and they don't say what those signify or even if they won't help. It's just the usual "can you test your memory in another computer" routine. I basically have a $2k brick sitting on my desk due to supermicro.

Overall Review: I will never look at supermicro when buying any motherboards again. You might win the lottery and have a working one and never have to deal with them but I lost and their support was awful and slow.

Pros: Minimal footprint and the easiest install possible. Chose this because I needed something that would fit a dual processor motherboard and also not stick out 4 inches from the motherboard.

Cons: It just didn't do the job. Probably my fault for choosing passive (I had no experience with passive heatsinks). I have a pretty intense application (dual 6 core procs running at 100% often) and my system would maintain 80-90C (didn't run it like this for long). I was using CHENBRO SR20969-CO case and bought an additional fan for an open space.

Overall Review: With the case open and a large fan aimed at the motherboard this did the job. For lower intensity applications or colder rooms with higher airflow cases this might be a great product.
