This review is from: Intel Celeron 430 Conroe-L Single-Core 1.8 GHz LGA 775 35W BX80557430 Processor
Pros: We have five of these running on Intel mini-ITX motherboards for our DNS servers. Quiet and low power...43W. In a 2U case, my experiments showed that we did not need any fans running. I decided to plug in the stock fan, but in 24H testing with the fan unplugged, our temperature remained low.

This review is from: NETGEAR 8 Port Gigabit Business-Class Desktop Switch - Lifetime Warranty (GS108)
Pros: Inexpensive, sturdy case, decent-design wall wart. Works well during the period that they work
Cons: I've now had the electrolytic capacitors fail in around 80% of units, and I'm sure the rest will fail soon. They use cheap parts, so they dry out and fail. Cheap aluminum electrolytics have become the scourge of the electronic industry; I have my Atari 800 system from 1980 and it's electrolytic capacitors are still good, though they're like 20 years past the failure point. These new Chinese capacitors can't even make it two years.
They save a few cents on the front end and make us pay for it in the back end.
I have much, much older Netgear "blue" series gear that still works, so they can make them well if they want to.
Netgear has TERRIBLE, AWFUL CUSTOMER SERVICE. Want to have some tech in "that country south of Nepal" talk down to you and tell you--that despite an MSEE and 20 years experience--that you don't know what you are talking about? Buy NetGear?
Other Thoughts: There is a lifetime warranty on these units, but based on my past experience, it is easier and generally cheaper to just repair them myself. Aside from the capacitors, these units do work quite well and I'm willing to put up with the general crappiness of NetGear because I can fix it myself in a few minutes, and once we fix them they STAY fixed. I ordered a fresh stock of nice Panasonic 105C caps from Mouser just for these stupid things.
If I could not fix them, I don't think I would even bother with Netgear anymore. If you're planning a large rollout (we used two for each overbooked student office), better buy some spares so you can swap them out as they fail. Better yet, just pull them apart from the start and replace all the caps. But we never seem to have time for that.
Did you know that NewEgg considers the name of the nation that contains the Indus river to be a dirty word?!? Neither did I.
Pros: Good, solid case. Comes with rail kit. Airflow is good. Fans are easily removed and are of good quality. So far, PS failures have been rare.
Cons: Tight. Very tight. The cases are built as big as they can get them, which means they tend to interfere with other equipment.
The big drawback is that they don't take the standard ATX I/O port back panel. If your motherboard does not fit the I/O panels provided, you may have to leave it off or have custom ones cut (we've started leaving them off in our data center when we remove a motherboard for repairs).
Other Thoughts: We have 128 of these cases. Calling a 400W power supply "inadequate" is hardly fair. This is more than we need for most of our machines which are number crunchers, not running a dozen hard drives or multiple gamer-grade video cards. We would rather have a smaller efficient power supply than pay for a giant one we don't need cranking out heat.
Supermicro cases seem to be built to a metric standard and therefore don't fit quite perfectly into industry-standard racks, which are actually made to an inch standard and were only "kludged" into metric.
These 2U cases fit fairly well, but the SuperMicro 4Ucases end up taking "4U and one extra hole" if you don't want them grinding the finish off each other or getting hopelessly stuck in the rack. This is the case in our newest Middle-Atlantic racks or our old DEC pdp11/70 Racks (one on each end of spectrum, you see). If we buy enclosures from CalPC, Antec or several other manufactures, they all fit fine in all racks.
