I'll write it here for your convenience:
Socket Type matches Motherboard's Socket Type
FSB lower or equal to Motherboard's FSB (not necessary but highly recommended)
Note: In the case of AMD, replace FSB with HyperTransport
Motherboard BIOS must support your CPU - only an issue with older CPUs
Must support your CPU, done many times by socket type or processor type
RAM type compatible with Motherboard (DDR2 DDR3)
RAM amount under maximum amount of RAM motherboard can support
Your RAM is divided in this manner:
If motherboard has dual channel, your RAM must be in a multiple of two
If motherboard has triple channel, your RAM must be in a multiple of three
Motherboard has one slot available for the video card (PCI Express, PCI Express 2.0 x16, etc.)
If running in SLI, both the video cards and motherboard must support SLI
If running in Crossfire, both the video cards and motherboard must support Crossfire
Motherboard has one slot available for the sound card (PCI Express, PCI Express 2.0 x16, etc.)
Motherboard has one SATA slot for each hard drive you have. SATA 1.5 GB/s and SATA 3.0 GB/s are compatible with one another.
If you’re running RAID 0, your hard drives should be the same
If you’re running RAID 1, your hard drives should have the same size
If you’re running RAID at all, make sure your motherboard supports the specific type of RAID you intend to use
Check which slot each drive uses and make sure there’s an available slot for each drive on the motherboard. Generally, each drive will take one SATA slot while a floppy drive has its own special connector.
If you use a floppy drive, make sure your motherboard supports floppy drives
Power Supply Unit
Make sure it has the connector that your motherboard requires. A 20+4 pin connector can satisfy either a 20 or 24 pin adapter on the motherboard.
If you’re using a single or dual core CPU, make sure that you have one 4 pin connector in order to power it.
If you’re using a quad core CPU, make sure that you have two 4 pin connectors in order to power it.
Make sure that there’s enough 4 pin molex connectors for all of your drives (usually not an issue because the molex connectors can extend off of each other).
If you’re using a floppy drive, you need to make sure that there’s a floppy drive (4 pin Berg) connector
Check your cards to see if there are any power requirements – sometimes the video or sound card requires power. If so, make sure your power supply has these connectors.
All of the motherboard requirements have been discussed earlier
Check the form factors on each of your drives:
Any drives that can be accessed from the outside (CD drives, Floppy drives, etc) require an external drive bay of the correct form factor (3.5 inch, 5.25 inch, etc)
Most hard drive today have a form factor of 3.5 inches – if so, then make sure your case has an internal 3.5 inch drive bay for each hard drive.
Check the form factor of your motherboard (ATX, Micro ATX, Tower ATX, etc.) Make sure that your case supports this form factor.
Check the form factor of your power supply. Make sure that your case supports this form factor.
Especially in small cases, powerful recent graphics cards have a tendency to not fit properly. If you’re purchasing a small case, find out whether or not large video cards will fit – this might require some work on your part.
If you need any advice, please do not hesitate to ask - I would be happy to help you
