5 out of 5 eggsAwesome Product!!!

Pros: The system is small which is wha tI was looking for. The dual core processor more than handles the Windows 7 Ultimate 32 bit OS. This tower is a must for a home media center. I also purchased the Audio Advantage Micro USB sound card from Turtle Beach so I can run full 5.1 digital sound for my home theater.

Cons: It woudl be nice to have DVI or HDMI out and digital out on the motherboard, but a few extra bucks solved that with a few additional USB extras. Only one PCI slot for adding an extra half height video card, but this also works surprisingly well for a media center application.

Other Thoughts: I am going to order another one of these systems for my brother in law's home theater system.
These mini systems are awesome!!!

4 out of 5 eggsGood *basic* computer

Pros: Cheap price, includes dual-core CPU, compact size, quiet, and low power consumption.

Cons: Front bezel/panel feels flimsy. It takes a lot of care to remove it w/o breaking the little plastic tabs. Hard drive placement is a bit odd, (it goes upside down and against the bottom part of the case itself). The Intel Atom architecture caps out at 2GB of RAM, so it's not as "future-proof" as other barebones kits might be.

Other Thoughts: If you're looking for an inexpensive media PC or every-day PC, this is the perfect kit for you. Add RAM, a hard drive, and if you want, an optical drive, and you're set. The upgrade options are somewhat limited, so you might as well max out the RAM and get a nice-sized HDD. I'm not sure if this computer could handle a blu-ray drive and movies w/o a separate video card, but the integrated one handles full screen AVIs, DVDs, and Youtube videos w/o issue. While there is no fan on the CPU, and the computer does remain pretty cool, there is still the fan from the power supply and one on the case, so there is a little noise. If this kit came w/ HDMI out, that'd be the perfect icing to this already tasty cake... :-)

3 out of 5 eggsAffordable and mostly works

Pros: Cheap, no frills box, easy to assemble, quiet, decent performance,

Cons: Intergrated NIC died after few weeks, had to buy PCI LAN adapter.

Other Thoughts: Solid machine for home media server. Standard Atom Gen 1 features (so no PCI-E, only 1 RAM slot ...)

3 out of 5 eggsDoes the job as WHS

Pros: Quiet, cool, reliable.

Cons: Case design could be much better, space isn't used very well. The biggest problem so far though - and maybe I'm just an idiot - but I bought a Rosewill RC-401EX 1Gb PCIe NIC and it just won't fit in the case. It almost appears that the PCIe slot in the Foxconn is in backwards. Can anyone tell me what I'm doing wrong? Has anyone else gotten something like this to work?

5 out of 5 eggsBasic WOW Finally

Pros: Finally a basic unit to do book keeping on that does not have too many un-needed features.. features that you do not need to pay for by the way. The price is fantastic and the performance for what I use it for is way more than adequate. The assembly instruction sheet is very good for putting together the hardware.

Cons: I did not need a floppy drive and the 3.5" external drive bay might be too crowded to try to get one in.
No instruction for the driver install but was not too hard to guess. The ability to go into standby and then come out on my unit works if you play with settings in bios a little. Not perfect though. Flimsy DVD cover.

Other Thoughts: Front cover is difficult, pay attention to instructions. There are three clips on the bottom. one at left, one about 4 inches to right of this one and one to far right. putting pressure at these three points is how you release them. If you do not read the instructions you will not realize that the 3.5" hard drive mounts upside down on the bottom of the case under the DVD drive at a right angle to the DVD drive. Unusual mount but it works great.

5 out of 5 eggsNice mini

Pros: Compact, low power consumption, Dual core Atom rocks. Love the low price for what you get.

Cons: Only 1 hard drive slot and 1 DIMM. Knew that when I bought it so it's really not a con.

Other Thoughts: Bought this to run as a Windows Home Server. Works great. Removed the DVD after installing and mounted a second drive for more room. Home Server only uses about 500Mb ram, so the 2Gig stick I put in it is more than enough. Works awesome.

Read the other posts about the fragile plastic clips, so I took it easy and didn't break any... thanks for the heads up.

3 out of 5 eggsWhat a pain...

Pros: Small case, low power consumption, nice exterior design. Integrated power supply is a bonus.

Cons: Interior architecture is TERRIBLE. With very minor modification, this case could house a DVD drive and four 2.5" hard drives. The PSU cords are too close to the hard drive, meaning it's impossible to mount a 3.5" drive inside the case - you have to remove the front panel and pretend the black part of the drive is really the black front panel.

Other Thoughts: Foxconn really messed up on this one. I have a 3.5" hard drive in the 5.25 bay, and a 2.5" hard drive stuck to it with double sided tape. I might rip the case apart and mod it with a proper hard drive rack and just remove the drive mounts that come with it.

5 out of 5 eggsdoes the job very well

Pros: Dual core with hyperthreading = QUAD
low noise, no real heat to speak of.
super easy to build.

Cons: front cover took me a few minutes to get off for the first time. i can now pop it off easily.
DVD eject button feels flimsy.

Other Thoughts: computer repair and building is my hobby so i do have a lot of hardware knowledge.
This is my first mini itx build and for what paid for the parts required it was a great CHEAP build.
now in hindsight for my purpose(Bluray) that i built it , i should have spent the extra $ and gone with a M-itx that has nvidia for the chipset. maybe next month.

all in all this is a great little desktop unit that just does what it does.

5 out of 5 eggsLittle Box o' Goodness

Pros: Cheap (case/mobo/proc combo), easy on electricity, nearly impossible to overheat, SFF, elegant case. On-board audio/video = simple and low-electricity.

Would make a perfect $200 simple desktop computer.

Cons: Not a powerful processor, but that's not what you were expecting right? ;-) Had a hard time installing OS from USB CD-ROM, used various ports but all worked well once OS installed.

2 SATA ports. Want more (or eSATA)? --> Low-profile PCI to SATA card

Other Thoughts: Now running as my home file/media/web/ftp/torrent/VM/VPN server under the guest bed. Use the suggested 2 GB kensington ram for its low-profile aspect for best airflow. Used 1.5 TB WD green HDD, low heat/power, high capacity, average performance but more than it needs for what I ask.

5 out of 5 eggsHassle Free Build

Pros: Everything went together smoothly, runs fast & quiet. Small form factor saves space on cluttered desktop.

HDD - Spare WD 160 Gb SATA. Fit right in with included cable.

LightScribe Drive - - fit perfectly, included SATA cable just right.

Card Reader - - there [u]is[/u] an extra USB header on the board for installing this type of accessory.

Memory - - Posted without complaint.

Overall, I'm very satisfied with this unit and pleased with the performance of the dual-core Atom running Karmic Ubuntu.

Cons: On-board graphics are adequate for an average SOHO desktop, but do struggle a bit. This kit would be really awesome with ION chipset instead. It would also be nice if the board could overclock the processor. For applications requiring heavy graphics or more processing power, this box leaves something to be desired.

Removing the front bezel is tricky - don't forget to replace the screws for the drive cage before you snap it back into place!

Other Thoughts: 5 eggs for sheer value.
