PCI L-Bracket Extenders

[K-TRON]

The Dell PCI riser I am sending you has two holes in it for mounting.
They are 1" above the PCI slot. The riser is 6" long, and the holes are 5/8" in on one side and 3/8" in on the other
The holes are large enough for 3/16" bolts/hardware

I would scrap that optical drive and get a small form factor mini SATA one from a laptop
You can also cut that media card reader down to save space. They are generally 75% hollow anyways.

Hey, does anyone know of any places online to buy custom-length standoffs, motherboard screws, PCI bracket screws, PSU screws, fan screws, etc? Putting the standoffs through 3/8" wood will require custom standoffs.

Yes I do,

If you need case screws and such tell me what you need. I have hundreds of extras I can send. You would need to buy custom standoffs from the link above

Good Luck

Now there's a useful website! I think the closest product to mobo standoffs are the male-female threaded hex. How do I go about finding my thread density on my mobo screws?

[K-TRON]

I wouldnt worry about the thread density of the nuts, just get nuts at a hardware store which fit the standoffs.
10-24 is common
10-32 is also common (this is the machine thread version of the 10-24)

The first number is the thickness. I am not 100% sure, but I believe everything under 1/8" diameter is governed by numbers 2 - 12

The 24/32 numbers are the thread pitch. The larger the number, the more threads there are per inch of material.
So 32 has finer thread than a 24 bolt.

First narrow your search and find something which can go through the material selected. The female threaded part can always be ground down with a grinder/dremel (so the motherboard isnt like 3/8" away from the wood)
Than get nuts from a hardware store or from mcmaster carr
