Pros: Standard "web-managed" switch. Standard options. Works as described. Regular "Web" or "Smart" management features - VLANs, etc.
Cons: -NOT- a true L2 "Managed" switch as described in the heading.
Overall Review: HP, but -not- a ProCurve which is a different class of switch. (aka Cisco (by Linksys) as opposed to a true Cisco)
Cons: Received two and both were DOA. Both locked up during Windows install then started throwing SMART errors in two different systems.
Overall Review: Must be a bad batch out there. I'm going back to the Black series in the future.
Pros: Typical Intel quality. No-frills board and great for business systems which I build. This is my current standard for business workstation builds. i3 CPU with integrated video in the processor is great and I feel much better than the motherboard video many boards have.
Cons: Parallel port would be nice because many businesses still have older non-USB printers but the motherboard does have the header and you can get an I/O panel bracket for just a few bucks if needed so it's not really that much of a con.
Overall Review: Previous reviewer mentioned that it's time to lose the PS/2 connector. I disagree. For business workstation builds, the PS/2 connector is a must - just try taking away a liked keyboard from a secretary type person that is PS/2 only and doesn't work with an adapter. They'll tell you to take it away leave their 7 year old clunker PC before they'll give up their old IBM click click keyboard.
One thing to note is this motherboard does -not- have video built onto the motherboard. It has the connectors for VGA which confuses some but you have to be using the proper i3/i5 CPU that has video support in the CPU itself.
Pros: I've purchased a number of these and they work great - both USB and eSATA. I'm using them to replace other external enclosures that have failed/failing fans or no eSATA support.
Cons: none yet!
Pros: Nice, no frills 1U case.
Cons: Hard drive(s) screw in from the bottom. No problem with that but it's at a slight angle so I'd recommend hooking up your power and data cables before screwing it down.
No USB ports on the front of the case. Other flavors of the SC512 do have them though.
Also, no rack mounting hardware included whatsoever, however they can be ordered separately or like above, other SC512 models include rails.
Not a con for SuperMicro, but Newegg should stock the proprietary powersupplies that SM cases use. They can be difficult to find and when you do, the prices are higher than what I'm sure the Egg would charge. If they sell the cases, they should sell the supplies. That said, I've yet to have one fail on the 30+ servers I've built with SM chassis.
Does not include the break-out connector for the front panel cable as many SM chassis' do. It's nice when/if using a non-SM motherboard.
Overall Review: Just keep in mind that this, and all 1U cases, use proprietary sized powersupplies. The cost of a replacement supply is not much cheaper than the entire chassis.
Also, it should be noted that this case is designed for use with certain SuperMicro motherboards. Others will work but the 24-pin and 8-pin ATX12V connector may not reach unless the connectors are right along the side of the board - you may need to purchase extension cables for both.
Pros: See my review above and additional comments below.
Overall Review: Just an addition to my review above. This is a high-speed 70mm and and as such, it's LOUD - hairdryer loud.
However, it's a 4-pin PWM fan and assuming your motherboard supports PWM (most all current server boards do), you can slow it down via the BIOS and/or OS utility. At full speed, it's LOUD, even for a server room, but again, that's the nature of the beast when you try cooling 1U cases.
Pros: As usual with SM boards, it works fine and is rock solid.
Cons: Pin-1 listing for the front panel connector is either reversed in the manual (both printed and online), OR the red stripe denoting Pin-1 on the SM SC512 chassis is wrong. Pin-1 is actually the one closest to the sATA connectors, or as I said, the chassis cable is incorrectly marked.
Overall Review: People seem to have alot of problems with memory on this and other SM boards - it's not an SM issue - it's the Intel server chipset. You will have the same exact problem with boards built by Intel/Asus/whatever.
People need to spend a little time learning the difference between buffered/unbuffered (registered/unregistered), ECC, etc.
Assuming you are using the right type, you should have no problem with any quality brand. HOWEVER, when you start populating all slots and/or plan to use higher capacity modules, you need to research what the board supports as far as single-rank, dual-rank, quad-ranked RAM and research what type your planned memory is. Again, this is a chipset limitation and not SM.
Thank said, SM would help ALOT of people and cut down on RMA's, if they would simply test readily available commodity RAM like Kingston, Crucial, etc. What they have on their compatibility list appears to be just what they have onhand and NOT readily available in the marketplace.
Pros: Works as advertised.
Cons: Not the best cooling but that's to be expected due to its size. As long as your case has decent cooling, you'll be fine.
The bottom of the heatsink has a piece of plastic film protecting the copper base and it says to remove before using. This film does not come off cleanly - it came off in pieces and left sticky adhesive residue behind that I had to remove with lighter fluid. Rosewill should seriously rethink using this type material.
Instructions would be a plus but even a monkey could figure it out.
Overall Review: Unless you are using a 1U case, there are better products out there. If using a 1U case and you need active cooling, this works just as good as other 1U devices.
Pros: See my other review.
Cons: See my other review.
Overall Review: Just an update to my previous review.
Current shipping models of this case are using an 80mm rear fan as opposed to the 92mm fan it used to have. Also, they have omitted the plastic shroud that directs outside air from the side vent to the CPU. The model number did not change.
Pros: Very nice picture. Blows away my 42" Sharp Aquos. It may be that the Sharp is 2 years old or that technology has changed in 2 years but the picture is much nicer than the Sharp.
Cons: 2 HDMI inputs - 3 would be nice.
Pros: I've done about 150 builds for corporate customers using this board. Only one came DOA and there have been no other failures. I've used a wide variety of memory with this board with no issues even though I normally use Wintec or Crucial. (No more Kingston for me after at least 10 failures in the last year with their DDR2 stuff.)
Having a parallel port is a great plus as there are many parellel only printers still being used in the corporate world.
PS/2 ports are nice and becoming less common - anything to save a couple of USB ports I'm all for.
Cons: None really!
Overall Review: There is little in way of overclocking features but that is normal for Intel boards and not really an issue as this board isn't positioned for that market.
I've been extremely happy with this board and hope there will be a similar one when the i5/i7/DDR3 world becomes more mainstream.
Pros: Excellent case for a business PC - good construction and has that 'tight' solid feeling of an OEM case like many Dell's do - a great plus when you have customers that may be a little leary of purchasing a no-name brand PC. Tooless drive mounting is nice, even though I do use the screws as well.
Cons: As many have said, the 3.5" bay should also be usable for a hard drive as most of us don't put floppies in our builds anymore. Internal USB connector should start using a single plug as all motherboards use the same pin-outs for many years now.
Without being able to use the floppy bay for a hard drive, mounting two drives in the provided bay ends up with the drives mounted right on top of each other - not good when it comes to cooling. You could use the 2nd ROM bay for a hard drive (with an adapter) assuming you don't have 2 ROM drives.
Overall Review: I've done over 500 builds for clients using this case in the past few years and the 523 series before it. Nice clean looking design which is great for the corporate clients - most cases out there are not appropriate for the business environment - either too ugly, too flimsy or too gamey looking.
Out of those ~500 builds, I estimate maybe 30 powersupplies have failed and most have been after a power outage. The included supply seems to be more sensitive than others to off-on-off-on type power failures common when the AC fails and which surge supressors don't help any with.
Pros: Fast - while I haven't ran any synthetic benchmarks on it, it appears to be as fast as my 150GB Raptor that died.
Cons: The 'ticking' really annoys me. My ears perk up and I feel doom coming on when I hear a drive making an unusual noise. Reading the reviews here it appears it is normal for this drive. I guess I'll get used to it.
Overall Review: This is my first RE3 drive and so far so good besides the 'ticking'. I have 6 RE2 drives in a Raid-5 array and two others JBOD and have been happy with them overall besides one failing after about a year.
Pros: Good cooling, works well. sATA2 speeds supported.
Cons: Fan could be a little quieter but it can be easily replaced with a quieter one. Would be nice to have SATA power connectors in addition to the 4-pin Molex ones.
Overall Review: I installed two of these to replace two Athena units. The Athena units vibrated loudly with a resonating buzz about every two seconds.
I'm happy to say these units do not exhibit the same behavior.
Pros: Works like it should, supports SATA2 speeds, can use either 4-pin Molex or SATA power connectors.
Cons: So-so cooling due to small 80mm fan. (drives run about 10-degrees C higher when mounted in these as opposed to the Coolermaster 5-in-3 unit that came with my case (120mm fan)).
Loud resonating vibrations.
Overall Review: I've had two of these for over a year in a CoolerMaster Stacker case populated with 500GB WD RE2 drives. Both exhibit loud resonating vibrations often - about once every two seconds. I resorted to wedging some match books between the outer drives on the side of the case to stop it. Same problem with both units so I assume it's a design issue.
Recently replaced with two Supermicro CSE-M35T-1B units and problem resolved. The Supermicro units have 92mm fans and better cooling which dropped my temps by about 10 degrees. Supermicro units can be found the Server Accessories area here at the same price.
Pros: Great board for a basic or business system. Will accept most current processors from the lowly Celeron up to the Core2 Quads.
Cons: Lacks any PCI-e slots but not an issue if you know you won't need them, i.e., a business system.
Overall Review: I've built probably 20+ systems for customers based on this board without any problems whatsoever. Rock solid as are most all Intel manufactured boards.
Pros: I use this case for business computers I build. It has the solid, sturdy feel of a Dell that business customers like - no flimsy plastic/metal feel. Nice looking case without the 'flashy' look that many OEM cases have which simply looks wrong in a business environment. Power supplies have been mostly trouble free. I've only had to replace 2-3 out of 100-200 builds.
Cons: None however a 400-watt powersupply option would be nice but really not needed for a mATX board.
Overall Review: I've used this case for builds for a couple of years. Before that, I used the Z523 line. Can't say enough good about it.
Pros: Excellent reputation and warranty, especially when needed. Kingston RMA was prompt.
Cons: One of two sticks was bad.
Overall Review: I believe Kingston may be in the middle of a bad batch because the same thing happened with a DDR2-677 kit a week ago. One of two sticks was bad. I've used Kingston for years and this is the first time this has happened and it did so twice in under two weeks.
