Pros: Everything you need minus the OS, perfect for a technician or builder with a little knowledge, or a Linux enthusiast.
A little dated but enough for a backup box or a media server [Media on Attached NAS] not hosting. Good for a young child's first box, setup and install Toolwiz Timefreeze. Specs are enough to run the basics.

3GHz Dual Core is adequate to power Windows 7 to Windows 10 and Linux. 4GB of DDR 2 6400 is enough, but the board in mine, [DQ45CB] supports 16GB across 4 slots [2 Open] My unit came with a 160GB Seagate 7200rpm not the 80GB described [Thanks EPC]. Perfect to make a very usable 120GB with a 29GB backup partition. I loaded Windows 7 Pro SP1 [Thanks EPC] All the Updates and Drivers after extensive testing of all hardware. For those that care, MS Experience Index 1.0 - 7.9 as follows
Processor: 6.5
Memory: 5.9 [Shared Max with GFX chip]
Graphics: 4.4
3D Graphics: 3.6
Hard Drive: 5.9

I have the extra ram around so I'll move it to 8GB and I bought a graphics card 9SIA1N83V74323 .. [which I regret, $42 GT 710] that I might through in, to boost the numbers and provide for better media play through my TV. I wish that I could have bought a refurbished card for $15 to $25 bucks but Newegg's policy of not at least confirming inclusion of the low profile plate means I will never waste my time with those.

Cons: One minor scuff, not a con, but just pointing out that these are refurbished, such things should be expected.
One issue, the unit's BIOS has an Intel feature [Intel Active Management Technology] on my unit's Intel DQ45CB motherboard, that caused the unit to power up for a second and power off, every few minutes. Fix is Below.

Other Thoughts: On the Intel DQ45CB - Enter bios with F2, navigate to Intel ME.
The default password is admin (case sensitive), you have to change that to a strong password before proceeding.
Your password has to be 8 to 32 characters long and must have at least one upper case character, one lower case character, one number, and a special character like !,@,#,$,%,^,&,*.
Then go to IME configuration and change manageable feature from Intel AMT to none.
Save and Exit! Thanks FritzWue

Pros: Solid specs, quick shipping, ridiculous low price

Cons: Only one was available at the time I ordered.

Other Thoughts: No operating system was loaded, but the unit I got came with a Windows 7 Pro 64-Bit COA which worked fine for the OEM Windows 7 DVD I have. It activated fine.

Pros: even with out all the free upgrades I was sent, Its truly a nice box, even sent a free usb keyboard and mouse.
got it days

Cons: none

Other Thoughts: I see in your future...lots more Biz from my shop

Pros: Outstanding performance for a 55 DOLLAR computer. It definitely can be classified as an affordable super deal for those who are "poor and need more". It even came with a keyboard and mouse!!

Cons: None to speak of.

Other Thoughts: This is definitely a great seller.

Pros: I bought the computer to work as a home media server for Windows 7, to serve up Windows Media Center to my Xboxs. It is plenty powerful to stream TV and my video library, and you can't beat the price. It also has 6 SATA ports, a PCI-E slot, and 2 spare memory slots, if you have some extra parts lying around to put in it. A great little computer for the price!

Cons: The case is compact design, and the hard drive bay layout puts the connections very close to the left side of the case. For that reason, if you're adding another hard drive, you must use 90 deg SATA connectors. Not a huge downside, but something to be aware of (I accidentally broke a SATA connection off one of my hard drives trying to close the case, using a regular SATA cable...)

Other Thoughts: If you're looking for a cheap home server, don't hesitate. This will do it, and the price can't be beat for the specs!

Pros: low power

Cons: BIOS written for a PS2 Keyboard, and motherboard has no PS2 ports.... you guys wasn't really thinking when you made this did you?
cant access BIOS is a very big con for me telling stuff boot different places impossible
came with no drivers cd, lucky system was labeled motherboard intel DQ45CB, with a very annoying beep at power on

Pros: Had intended this to be a dedicated Linux computer, so no OS preloaded was a plus, along with its price.
Very fast, even with demanding distro's. Mine actually came with a 160GB HDD, so free bonus, yay!

Cons: Frankly, None!

Other Thoughts: Everything was recognized correctly out-of-the-box in both OpenSUSE Tumbleweed and Manjaro.
