I recently purchased 10 of these as part of an office upgrade. So far we have been extremely pleased with each one. After a quick QA run, they were outfitted with Intel Core i3-3220 Dual-Core Processor 3.3 Ghz 3 MB Cache LGA 1155 - BX80637i33220, and have been running smoothly since.

The included SATA cables were of nice quality, with clips and 90s on one end.

The gigabit adapter works well enough, and most of the drivers can either be slipstreamed or installed silently with a bat file.

The only main downside is the lack of a DVI adapter, and it's exclusion is a mystery. If DVI is a must, you can pick up some HDMI -> DVI adapters for a few bucks online and it should work fine.

Highly recommended.

Bought this for a mini tower budget build a couple of months ago and I have no regrets. It was easy to set up. The BIOS is user friendly. The driver disc was so-so. It has all the necessary drivers but a lot of the extra software is just bloatware for most users. Thankfully you can pick and choose what you want to install. As for the board itself it's got about everything you'd expect from a good microATX mobo. I like the USB 3.0 ports. If you're shopping around the price & the specs speak for themselves. At it's price point it's hard to beat.

I just built my first custom desktop and used this MOBO. Reason for this is because I wanted cheap and something with a lot of USB 3.0. I have a Phantom 410 case and I have 6 USB 2.0 and 4 USB 3.0 working ports. It's amazing. The max RAM on this MOBO is only 16GB though. I don't care about that because I have 8GB of RAM and my Samsung EVO 840 SSD is making this baby run like Jesse Owen's in 1936! Be careful of using PNY 8GB RAM because I got the BSOD from it. It only happens when both 4GB RAMs are installed and works fine with just 1. I tested it like crazy but then again anything can happen to anybody's.

Here's my build -

MSI LGA1155/Intel/MicroATX Motherboard B75MA-E33
Intel Core i3-3240 Dual-Core Processor 3.4 Ghz
Samsung 840 EVO-Series 120GB SSD
Optiarc DVD+R DL Overburn up to 8.7GB
Corsair Builder Series CX 430 Watt
Phantom 410 Case

The RAM is now Corsair Vengeance Blue 8GB and not PNY 8GB 1033 because that was giving me the BSOD

Nice little bare-bones board with the essentials. I'm using it with an i5-2500K that I pulled from an Intel motherboard that died and so far it's working great.

As usual, be careful when installing it - not to scratch the board with the standoffs when securing it to the case.

Some thoughts:
* The B75 chipset is "built for small business" according to Intel
* NOT for Haswell (4th generation) processors
* Works with Sandy Bridge and Ivy Bridge CPUs
* Only requires a 4-pin CPU power connector (not 8-pin)
* Only two DIMM slots
* No DVI (but does have HDMI and VGA output)
* Could do without the PS/2 ports, at least for me... haven't needed them in years
* Only one SATA 6Gbps port, the rest are 3Gbps
* I couldn't find an updated BIOS on the MSI website for some reason... they only have version 1.0 dated 2012-06-12 for download. I have no idea why but my board came with a later version of the BIOS.

It works well in this nice budget case: Cooler Master N200 - Mini Tower Computer Case with Fully Meshed Front Panel and mATX/Mini-ITX Support
I am also using this power supply: Corsair Builder Series CX 430 Watt ATX/EPS 80 PLUS (CX430)

Really cool looking board with good instructions and necessary hardware. I was very happy with it...for the first 4 days. Then it just displays 99 on monitor. Wont boot or do anything. Checked all my connections, everything i could think of. Board is defective so i'm sending it back. The price was great, but now I have to rebuild machine again. Not happy.

Ordered two of these to build two basic level desktops for my folks:

Additional Parts:
Intel Pentium G2120 Dual-Core Processor 3.1 Ghz 3 MB Cache LGA 1155 - BX80637G2120
Corsair XMS3 4GB (2x2GB) DDR3 1600 MHz (PC3 12800) Desktop Memory (CMX4GX3M2A1600C9)
Kingston HyperX 3K 120 GB SATA III 2.5-Inch 6.0 Gb/s Solid State Drive SH103S3/120G

Pros:

High value for low price
Supports DDR3 1600 after X.M.P. change in BIOS
Included two SATA III Cables (Black and White color scheme)
Lots of USB 3.0 ports
HDMI Port
1 x PCI-E 3.0
BIOS allows for mouse navigation and has lots of options for overclocking and power saving
Supports legacy mouse and keyboard interfaces (circular PS/2 rather than USB)
Can load web browser from BIOS after installing MSI software

Cons:

Memory defaults to DDR3 1333
No IDE interface
Only 2 RAM slots
1 SATA III slot
System Fan 1 placement on motherboard makes it hard for front fan to reach, also why 4 pin rather than 3? Odd.
B75, meaning a large number of advanced features are not present or very weak: no or little support for high speed ram, weak over clocking, no RAID, no support for SLI/Crossfire for multiple graphics cards and no Intel Smart Response Technology (SSD Caching)

Both systems are working fine, startup times are 10 seconds on Windows 7.
