Pros: Many SATA and Molex connectors if you intend to fill an Antec 300 or 900 with drives. If you mount the PSU "upside down" with the fan up, the Antec logo on the visible side is right side up. Decent combo price with Antec 900 case. 120mm fan is quiet.

Cons: I wish the 8 pin ETX and 4 pin ATX motherboard connectors were module. I only use the 4 pin, so the 8 pin is just tied up in the bottom of the case. The SATA connectors are oriented so that starting from the PSU, the first connector should be the top most drive. I wish this was the opposite for bottom mounted PSU cases.

Overall Review: This has many connectors for connecting many SATA and IDE drives. Permanent direct connections include: 1 x 20+4 Motherboard 1 x FDD 3 x Molex 3 x SATA 1 x 6+2 PCIe 1 x 4 pin ATX 12V 1 x 8 pin EPS 12V Up to 4 of the following can be connected: 1 additional 4 pin PCI-E SATA cable each with 3 SATA connectors, 2 cables included Molex cable each with 3 molex connectors, 2 cables included If you only use 1 PCI-E connector, a maximum of 9 SATA drives and 9 IDE drives can be connected without using any splitters (as long +5V and +12V long are not exceeded).

Pros: Powers Phenom X4 9600, 3 hard drives, and a Radeon 4830 with no problem. Quiet.

Cons: If you need a UPS, plan on purchasing a double conversion or online pure sine UPS. My computer will reboot when power goes out when connected to a 1500VA APC or Cyberpower simulated sine UPS. The computer will start while on battery power, but will reboot when transfering from the line to battery power.

Overall Review: Phenom X4 9600, Asus M3A78-EM, 8 GB G.SKILL DDR2 800 (4 x 2GB), ASUS Silent Square EVO, Antec 300 Case, HIS H483FN512P Radeon HD 4830, 2 X WD 320GB Caviar SE RAID 0, 1 x WD 1TB Green, Antec EA500 PSU, 3 x Scythe SFF21E.

Pros: 3-Pin Chassis and 4-Pin CPU fan headers are regulated using Q-Fan. When using HSF with an older 3-pin connector such as the Zerotherm Nirvana NV120, the HSF can be connected to the 3-pin chassis header instead of the 4-pin CPU header. Northbridge heatsink is no taller than standard height ram; it does not interfere with large CPU HSF. SATA RAID 0 works well.

Cons: Documentation indicates Q-Fan only controls the CPU header. On 1 build, I thought I could connect a Scythe SFF12E fan to the chassis header, but I noticed it did not run at full speed with Q-Fan enabled. Q-Fan 2 regulates both the Chassis and CPU fan headers.

Overall Review: I have had no major problems with 2 out of 2 systems built with these boards. Both builds: Phenom 9600 BE, 8 GB G.Skill Ram (4 x 2GB running at 800Mhz).

Pros: Phenom X4 9600 stays under 33C idle and under 47C fully loaded. Whisper quiet when connected to Chassis connector on Asus with Q-Fan 2 enabled. Fits on Asus M3A78-EM in any direction with standard height memory installed. With tall memory installed, it may still fit when mounted blowing towards the rear of the case, but not when blowing towards the top of the case.

Cons: It only has a 3-pin connector. It runs at full speed when connected to a 4-pin PWM connector. The fan cannot be replaced.

Overall Review: It comes with a white manual speed controller, but I prefer an automatic temperature based control.

Pros: 640 shaders were already enabled when it arrived. Cool and Quiet. With Folding@Home GPU running the GPU load to 97%, the GPU temperature maxes out around 55C.

Cons: The fan speed is not reported in GPU-Z; always running at 100%.

Pros: The side fan mounts below the video card; the fan does not block large CPU coolers. This case is very discrete; without additional LED fans, only 2 blue LEDs (power and hard drive) and a faint blue glow through the front fan (from the CPU cooler) are visible in the dark.

Cons: My Radeon 4830 blocks 1 internal 3.5" hard drive bay. USB and headphone cables connected to the front port will catch on open DVD/CD drives. The power button is very close to the DVD open button.

Overall Review: An Antec 300 plus 3 x 120 mm fans is almost the same price as an Antec 900 (front fans included). Phenom X4 9600, Asus M3A78-EM, 8 GB G.SKILL DDR2 800 (4 x 2GB), ASUS Silent Square EVO, Antec 300 Case, HIS H483FN512P Radeon HD 4830, 2 X WD 320GB Caviar SE RAID 0, 1 x WD 1TB Green, Antec EA500 PSU, 3 x Scythe SFF21E.
