Macintosh LC II Mod

looking good bud, my question is u gonna make ur own block? (cnc)
 
No, I can't make it myself, don't have access that sort of equipment.
 
Looks like it might be rather impossible to fit the PCIe flexi-riser in there......to be sure if it's not impossible, it'll be a puzzle in and of itself ;)
 
I think it's possible, the riser board will fit like this

and the ribbon is a bit of a pain but I'll run it over the top and is should get there. will be rather long though, about 230mm I think

Right guys, conceptually nothing much has changed recently. I have been sketchupping a lot though, looking up dimensions and doing things properly.

Here's the latest design for the heatsink, those screws look crap so I'll change them.

Now I'm currently working on sketchupping the tubing, the pump and the res. Pics to come.
 
This is impressive and ambitious. I wanna see the end product!
 
countersunk black allen bolts would look better then them screws :)
 
what an insane idea! subbed. I'd like to think there is a better way to situate that low profile gfx card, but given you've run all the dimensions, you might well be onto one of the only possible combinations. and a 5750 IMO is plenty of power for the kind of unique system you are building, pair it with a 19-22" monitor, and when you rock up to lans people will be utterly amazed, especially when you say its w/c.

:toast:
 
interesting build there my friend. cant wait to see it up and running!! subbed.

:rockout: :pimp: :respect:
 
Agreed. Awesome build idea. Subbed.
 
use a slimline dvd drive and get a pico PSU

A pico PSU with a HD5750 ? That's not going to work.

Of course, he could use two of those and split the load between the two, but that's going to be relatively tricky.

sure it would depending on what wattage he got. and splicing PSU's isnt all that hard their are multiple people on this forum that have done it and their are guides on doing such. it really isnt a difficult concept.

I believe the highest-rated Pico-PSU is a 150W one.
 
Could take a cheap brand psu remove the other casing dump it inside the case and instead of high rise metal heatsink inside the psu put a 120mm right on it. just suggesting but dont know if it will fit.

Definitely. The screws are just placeholders!

Thanks. I have tried a lot of combinations and every method means some sort of compromise. I can mount the gfx card in an orthodox fashion but then I would have to mount the PSU somewhere strange and have it hanging out. Ultimately what I have come up with is the most space efficient. It's not perfect but it is very interesting and the idea of this waterblock is a lot of fun to try to design so even if there are better ways I like this way.

I do have a slimline DVD in there......

I did consider picoPSU, you can get PSUs designed for in-car applications that do 250W which would almost be enough for this computer.... but the more watts you want out of the DC-DC PSU the bigger power brick you have to get, and those high wattage power bricks are hard enough to find let alone pay for.... so i'll give that a miss for now thanks.

I'd rather not use a cheap PSU. But I see what you are saying and I will certainly be open to modding whatever PSU I do use, might free up some space. Don't really like the 40mm fans that come in flex-ATX and 1U PSU's, noisy little fuckers.

This is the (almost) final layout. I have labelled a few things for you (I know some of them are pretty obvious!) and also put in some arrows to show the cooling loop.

New since last time are the pump and fittings which I have modelled myself, the tubing, and the reservoir. I was greatly inspired on the reservoir by craigbru's Project Hutch . The thin sandwich acrylic should work nicely here, there is the angle in the case which gives some fall along the res and the res where it is can feed the pump from above which is ideal.

Looking great. I might just get into this sort of thing in the future.

I would suggest painting the front of the optical drive to make it match the shell of the LC as much as possible. Either that or get a slot-loading one! Then all you'd have to do is extend the floppy drive slot.

Just a word of caution, a res right over your ssd/hdd's may be a questionable idea. All the times I had leaks was due to my res.
 
I love retro-builds. Looking great... and nice job on the CAD work.

I wouldnt advise the offset/angled squeezed design. I think you are asking for more headaches and heat issues. I would think "out of the box". Get that radiator out of the box and free up some space. Why not pick up an old mac accessory like this and turn that into an external rad case?

yes, I know that the is an EVEN EARLIER generation accessory that doesnt really fit the LC, but the old logo is beautiful, it has a metal case good for heat dissipation (you in the plastic pizza box original design is going to struggle to get the heat OFF the radiator) and the whole combination would fit together aesthetically. The "in use" LED would look cool. You could even get it to change colour depending on temperature of water. Or if that was too tricky, then just use it as the HDD LED.

Oh yeah definitely going for a slot-load. Maybe it doesn't look like it in the pic but it is supposed to be. Once the floppy slot is a bit longer no one will ever know.

OK I'll keep that in mind. Maybe I can put in some drip-shields or something....

Thanks for the input, that would definitely be a cool idea and using an accessory box is an idea I have toyed with but not for the rad, I was mostly thinking for the PSU. Ultimately I want to keep this all-in-one and am willing to compromise in other areas. If I build it and the thing overheats and melts down, I won't come crying to you, promise!

Besides that sort of stuff is hard to find in this country
 
That looks really nice, I especially like the all-in-one WB.

What CPU are you planning on?

And do you think that you can cool everything with a 140.1 rad?
 
Reservoir

Could you not put the reservoir in the long foot at the front of the case or would it be too small and awkward to work with?

I was thinking of getting a 910e . If I can find one. Keeping it low power should mean the 1 rad will suffice.

Perhaps, but I wanted to mount the res at the high point in the case, so it is above the pump
