Right, this is meant as a reference for people who have some idea what they're doing.
If you get stuck or have no idea, post in the forum as people will be able to help you better than this generic guide to everything.

*These are non-standard, generally manufacturers making memory faster than specified (mainly for overclockers)
Heatsinks (ramsinks)
Ramsinks do /not/ help the memory cool, but they can help keep temps stable which can help with system stability.
Generally don't bother unless they came fitted on your memory
Motherboards
Sockets
See CPU Socket Guide
Multi-GPU
Specific technologies will be covered in depth in the graphics card section.
For a motherboard to be able to support a multi-gpu technology it has to specifically made to do so, this usually requires The motherboard to have;
A Chipset which supports your chosen technology (either Nvidia's SLI or ATI's Crossfire) A pair of Physical PCI-E 16x Slots (often only the primary slot will be 16x electronically, with the secondary being 8x electronically)
Layouts
Motherboards are often laid out similarly, but there are Differences with the placement of the cable connections, often these differences can make some motherboards unusable with some cases, also certain placements of cables can restrict airflow and impede cooling.
Badgers
Heatpipes
Some makers use heatpipes for cooling components on the motherboard,
However the heatpipes used often do not work as well if the motherboard is used flat or upside-down (as in lian li v1000 etc)
Optical Drives
Types
- CD
- DVD
- HDHVD
- BluRay
Common problems
Interfaces
Optical drives will talk on PATA or SATA (the latter being less common, but now coming down in price)
Hard Drives
Types
- 2.5" (Laptop)
- 3.5" (Desktop)
longitudinal perpendicular
Interfaces
PATA, SATA, Blah
Cache
2,8 or 16MB
Speeds (RPM)
Common speeds are
- 5400rpm
- 7200rpm
- 10000rpm
RAID
Redundant Array of Inexpensive Disks
Most common RAID levels:

RAID1
RAID3
RAID5
RAID6
RAID10/01
RAID50
Common problems

Sound Cards
Soundcards are another oft overlooked component of mid-range computers for reasons we'll cover below.
Onboard vs. Soundcard
Onboard sound can be a great feature for family desktops and non-gaming machines.
However, as onboard sound uses the CPU for Processing sounds there is a risk of gameplay affecting performance issues when using onboard sound.
Also onboard sound can often pick up noise from interference on the motherboard which can sound like very quiet pops and clicks, this is often only a problem on headphones as speakers aren't sensitive enough to pick them up and any digital outputs aren't prone to the interference, but is worth a mention nonetheless.
Soundcards use a dedicated processor to process sound information with negligible load on the CPU, this improves overall performance including higher framerates.
Recommended cards
audigy/audigy 2, SBlive.
Surround, digital etc.
Surround is an area where onboard sound can excel in the price/performance field as many onboard sound systems support 5.1 or 7.1 surround over analogue and digital
You can also run a full analogue or digital surround system on your onboard sound for media purposes, while keeping a soundcard dedicated for gaming.
Power Supplies
General
Power Supplies (PSUs) are the most often overlooked and underspecced component in a computer.
Often a poor PSU will cause system instability, unexpected problems and can lead to component damage.
Wattages
Before we get into how many watts a PSU needs, we need to understand the ways it can be measured
Wattage on a PSU is usually quoting peak output, or sustained output.
Peak output (what most cheap PSUs are measured in) refers to the peak wattage a PSU can put out for a short period of time (seconds) often these will be fine for a while, then will develop issues (from being overloaded) and die horribly, potentially killing other components
Sustained output (nice PSUs) refers to the output the PSU can give all day every day without issue, sometimes a PSU that has a sustained output will also mention a peak somewhere such as "650W (710W peak)"
How big a PSU do i need?
If you're running a single GPU system, you'll need a 450W PSU max.
If you're running a dual GPU system, you'll need a PSU around the 550-600W Mark
Modding
*DANGER*
Anything within this section will probably kill you and your family if you fuck up
Fan Speed mod (also fan replacement)
Cable sheathing (pffft. sheath)
Case replacements, just don't, bad chav.
Cooling
CPU Heatsinks
Graphics Coolers
Fans
Extreme Cooling
Pros/cons of Watercooling
Pros/cons of Refrigeration
Cases
Types
- Standard ATX
ATX is your bog standard form factor from the past few years. Chances are if you own a computer it's living in an ATX case
- Upside down ATX (notes about not BTX)
Some ATX cases mount the motherboard upside-down as it can allow for better cooling and cleaner airflow.
These cases are often Called BTX cases by people who don't know better, BTX is a separate standard covered below, Upside down ATX cases adhere to all the ATX standards, but hold the motherboard upside down.
- BTX
BTX is a new form factor designed to replace ATX while offering better cooling and better designs for components
- SSF
SSF is not a form factor, but is a terrm used to describe cases such as shuttles.
- Mini-ITX
Is a very compact form factor designed by via, often used for in-car PCs and home-theater PCs as they're low noise, very low power consumption and heat output.
