Virgin Modder - Lian-Li V2000 Plus Top Blowhole

Am pleased with case but think adding a top 120mm blowhole will improve the exhaust ventilation. This blowhole may be extended later if i go watercooling.

Have got a dremel & have a 114 holesaw on the way.

My plan is:-
1) Mark & drill fan screw holes.
1-1) case upside down on wooden bench/block
Use No8 2.5" screws to centre fan screwholes
http://homepages.nildram.co.uk/~chsmith/FanScrew.jpg
Tap screws to mark screw holes.
drill screw holes.

2) Mark Centre point.
Mount screws into drilled screw holes & use 2 elastic bands to show centre point Courtesy of xmetrix - Cutting a "blow hole" Drill arbor hole.

3) Drilling Blowhole
At this point i think it may be easier to follow xmetrix's advise & turn the case right way up & mount a piece of wood to the inside using screws through new fan mounting screw holes. I think this would give the easier access when drilling the blowhole rather than try to do it from inside the case.
The drill needs to be on its highest speed for the holesaw i think.

4) If necessary clean up with dremel.

This is my 1st real case mod & i don't want 2 mess up my new case so any advise on above procedure greatly appreciated.

thanks

Which type of holesaw have you ordered?

As for drill speed, you'll need to follow the instructions for the saw you've bought. But, regardless of speed, stop at very short intervals and allow the saw and aluminium to cool before cutting again. Also, helps save the drill from damage.

To get rid of the rough edge when the hole is cut, you'll be better off using a small rounded metal file rather than a dremel. A dremel will do it, but you'll have a lot more control using a simple file.

If possible, practice on some scrap aluminium first.

You'd be better off using some long bolts, not wood screws.

metal-metal drilling/cutting requires lubrication. I have a little tin of "metal oil" (brandname, i guess) just for this purpose.

If you check my casemod thread, you'll see three smaller holes in the top of the case...guess which one didn't get no lube!

Proper cutting-fluid looks like milk. It cools as well as lubricates. Any oil will do, so long as you don't let things get too hot!

Nearly there

Stripped of masking tape.

Not sure how the scratch got there ??. Very clean hole took very little filing to clen it up.
3) The finished article
http://homepages.nildram.co.uk/~chsm...ture%20124.jpg
Will take the fan blank i cut out to halfords & get a paint match, want to also see if i can get some mesh like http://www.kustompcs.co.uk/acatalog/info_1345.html
Inside

if i ever see any one with any stock

All in all i'm pretty pleased everything went pretty well, bit difficult to see what it's done to my temps given the current heatwave

luck
