Some of you may remember my Velocity Micro/Lian Li case. It came with a "mystery" slot in the rear of the case which looked perfect for a GPU cooler. I searched everywhere on the net for an item produced by Lian Li designed for this slot, as it had 4 mountsing holes for thumbscrews. I did manage to find this

-But it wasnt available for sale anywhere I looked. I even contacted a helpful tech at Velocity Micro to assist in contacting Lian LI themselves. No Luck. VM told me they had tried a few of these in test-rigs and they werent impressed. She would have sent me one free, but couldnt find one anywhere.
I had to make my own, and while some of you were nice enough to compliment the looks, I hated having to do it. The only upside to it, was the plexiglass I used to make it with, along with a hacked clear casefan, allowed the noctua fan visible. Personally, I dont think it made things look "clean". (and ya gotta love the blue painters tape sealing it)

Its been about 4-6 months since I looked for this item, then recently spotted it online for sale & had to have it. Also noticed Lian Li is finally including a few of these in some of their cases nowadays.
Heres it is installed

First thing to do was rip out the lian-li fan & replace with my Noctua 120mm 1200rpm fan. The only issue I had with this item, was they really dont give you much room for airflow if you keep the fan installed "inside" the aluminum housing.(The fan itself takes up 3/4 of this unit.) And if you remove the fan & mount it "outside" the housing,(to eliminate backpressure) it hits the GPU's. So, time to mod & drill.
This aluminum housing is 2 pieces fitted together, overlapping, similar to a showbox lid.
Remove 6 screws, open it up some, re-drill, reassemble, done!

You can see the old screw holes compared to where the screws are now. In the end I got about 1/4" extra airspace inside which probably improved airflow by +40% over origional design IMO.
This is another stupid little mod barely worth mentioning, but I appreciate the help & info I get here, and wanted to pass this along. Definately worth the $25 for an alternative to a squirrel or slot cooler.
