5 out of 5 eggsWorking Since 2011 24/7

Pros: All I can say is that It's been running since 7/20 2011 24/7 with no issues. I installed two 4GB sticks of ram, two 1.5 Hitachi Deskstar drives, Xeon E31220 and Windows 7. .
It runs an intranet page, Vipre Business server, GFI Events Manager. Only reboot it when Windows requires it for updates.

Cons: None

5 out of 5 eggsVery pleased

Pros: Very pleased. I'm using it with an i3-2120 and 2 x 2.5" HDs and it's been in service since April 2012. It measures in at 28W on my APC UPS, awesome. I'm running Server 2008 with no problems whatsoever. Will be getting 2 more for Svr 2012 in a few weeks. Fits great in a 24" deep rack nicely. There's space for 2 x 3.5" drives but if you get 2-gang brackets like the Kingwin HDM-225 you can put 4 x 2.5" drives in no problem.

Cons: Not really a con, but the blue power LED on the front can literally light up a room at night. Kinda like looking at the sun. I disconnected it since the green HD and Ethernet LEDs are almost always showing activity, hense power...

Other Thoughts: Maybe slightly quieter fans, or better control over thier speed. With a system consuming a total of 28W from the wall you hardly need much cooling. It's certainly not a problem though.

2 out of 5 eggsbetter service needed

Pros: Love this system. I'm using it as a render node for 3ds max and it works extremely well.

Cons: I was trying to get the CPU temperatures as low as possible so i redid the thermal paste a few time and like an idiot i over tightened and put a small crack on one of the crew holes on the back plate that holds the heatsink in place. Buying the heatsink from their estore only gives you the heatsink, it doesn't come with the back plate that holds it in place which is ridiculous. I'm taking eggs off because I've been trying to get a replacement from Asus and they don't seem to care or even want to bother with it.

2 out of 5 eggsReliability Concerns

Pros: quiet, rack rails, inexpensive, BUT --> read the cons and comments before you waste your $$

Cons: I3 only, ECC only, BIOS does not properly report ECC so memtest86+ will not test as ecc.

Other Thoughts: I have four of these machines, one returned for failure (dead after three months) and another one is dying -- 50% in less than a year. Random errors, segfaulting in random places. First thhought it was memory (memtest spewed a bazillion errors). Changed memory from 2x4GB Kingston 1333 ECC 9/9/9/24 to 2x4GB Corsair 1066 7/7/7/20 (all my local guys had for ECC). Memory errors went away -- probably because of the lower speed -- but OS still segfaults and corrupts disk (Gentoo 3.4.9, 64bit multilib). It's the server for sure (confirmed not the disk -- tried two, they work perfectly in other faster machines) not the cpu, not the memory. These servers are flaky and the ECC/BIOS problem has been posted elsewhere. Apparently ASUS coulnd't care less about this problem. I regret buying these, for sure...

5 out of 5 eggsVery good value for price

Pros: Small compact rack mount system, includes rails and dvd drive. Also includes ASUS management software if you are stacking a bunch of these in a rack. CPU supports Xeon series - so you can get quad-core w/ 8 meg cache.

Also supports a RAID PCI-Express x16 card.

Cons: The hard drive bays are somewhat hard to access and there is only two, but you're only paying 430ish so it is worth it.

The board does not support any integrated graphics controller that comes w/ the CPU and is picky about the types of memory that it supports (although it does do ECC - which is win).

Other Thoughts: Put a couple of western digital greens (2tbs a piece in it), 16 gigs of ram, a raid card, and a xeon. Powered it up and got it functioning rather quickly.

I'm running RHEL 5.5 on it, and using it as a fileserver w/ the drives in a RAID 1 configuration.

Very good investment for the money if you're looking for a single CPU system, since it comes with rails (which many small bare bone servers do not).

5 out of 5 eggsExcellent 1U Server!

Pros: Excellent layout for a 1U, low-depth case, has an Asus P8B-M motherboard, comes with a PCI express riser. System runs cool. No driver issues with Server 2008 R2 64-bit. Runs cool, and fans are quiet.

Cons: Limited room for expansion, but it's 1U!

Other Thoughts: System specs:
-ASUS RS100-E7/PI2
-Intel Xeon 1230 3.2 GHz Quad-Core
-8 GB Kingston DDR3-1333
-Western Digital 160GB Caviar Black
-Samsung Spinpoint M8 HN-M101MBB 1TB
-2 x Western Digital 750GB Caviar Black
-Intel SASUC8I RAID Controller

To make the laptop drives fit, I used a Kingwin HDM-225 adapter, took a bit of drilling to make it fit.

5 out of 5 eggsQuality

Pros: Nicely laid out, holds 2 HD's, Cables were pre-routed, for the price, this ASUS chassis is ridiculously nice. No complaints, and there shouldn't be if you do a little studying and make sure all your components will function together. Compact!

Cons: None so far.

5 out of 5 eggsGreat little server

Pros: This is great little powerhouse server. It runs quite quietly and with the optional KVM chip can be fully managed remotely.

I installed a E3-1230 processor and 8 gigs of RAM and it easily hosts a couple of virtual servers.

Cons: The only downside to this machine is that there are a limited number of vendors making the correct ECC nonbuffered RAM which is REQUIRED.

Other Thoughts: I have a little datacenter in my closet at home and happily hums away all day long.
