RAM

Pros: Low profile - no higher than the clips on the slots. Low voltage - runs cool Low CAS
Cons: None
Overall Review: Relatively inexpensive for 32 GB. Very inexpensive for low profile, low voltage, AND low CAS.
Poor quality

Pros: Good looking. Nice heatsink. Does a much better job than the standard ones found on most memory.
Cons: Doesn't work at any speed. Two modules failed memtest86+. System restarts halfway through Windows startup with any number of modules in any slot on the board.
Overall Review: Would be great memory if it worked. I have a Rampage Formula with the latest BIOS. 4x2GiB of PQI DDR2-800 works just fine. G.Skill is the only memory brand I've ever had problems with in any board.
Typical Crucial SSD

Pros: Everything.
Cons: Nothing.
Overall Review: Too bad they don't come in 2+ TB sizes yet.

Pros: 8 cores significantly cheaper than equivalent Intel CPU
Cons: none
Overall Review: Way underrated. Certain well-known benchmarking applications are compiled with Intel compilers that turn off SSE support on non-Intel CPUs. Scores from such benchmarks are obviously totally inaccurate.
Pays for itself

Pros: At $0.15 / kWh, if your current PSU at its normal load gets you 84% efficiency, and this at the same load would get 92% efficiency, and you leave your system online 24/7, this PSU will pay for itself (plus an extra $80 that you save on top of that) within the warranty period.
Cons: Have to spend an extra $100 on a nice set of individually sleeved cables.
Overall Review: Several reviews (here and on other seller's sites) have complained about the power cord to the wall being "non-standard". They are wrong; it's a perfectly standard IEC 60320 C20 connector on the PSU end and a NEMA 5-15P on the wall end.
It's an SSD

Pros: All the regular SSD pros: silent, fast, low power, cool, small...
Cons: Windows-based firmware update tool doesn't work at all. Had to use the bootable USB version.
