Actually I've been thinking about how to go about with this mod... Lots to consider. Should I go with a regualr ATX Mobo? Due to the location of the PCI slots, it would have to be mounted upside-down as with the LianLi v1000. This would help with placement of the PSU as well. I'm thinking an acrylic panel to separate the PSU from the mobo. However, I don't think I'd have sufficient space for complete separation of PSU and mobo so.... Have to make some measurements...

Mac, i found this site,  he has the same G5 case as urs ...

hope it helps in ur modding venture

watch out, even for 1mb streamyx !!!

I've strong doubts about the prices on the G5 & the PSU ... 

Have not decided how to put the acrylic together... Glue? Screws? I've got the glue ready, SuperGlue is NOT a good idea as it will discolor the acrylic at the point of contact. Have tested the Selleys MultiGrip Contact Adhesive and while it takes longer to set, it provides a strong bond and will not discolor the acrylic.

Ain't no way I'm drilling through any fins. Anyways, completed the PSU mod the way I want it. thanks for the suggestions guys but if you were to see this in person, you will realize that airflow is really quite good. The wires had to be carefully folded out of the way in order not to block the intake fan.

Note that I've place the fan control rheostat and the on/off switch at the TOP of the PSU. This is intentional as I do not intend to cut the back of the case for the PSU switches. The layout of the
G5 will be such that the side of the case would be most accessible so this placement suits the case just fine...

Without further ado, here are the pics... Now to find some nice small (but longish) screws....

Ian, you must be psychic...

I've already glued the fellow. Tried the screws, too problematic. Will only be using screws for the top lid. Need to get access to the innards to clean/change fans if necessary. Gluing the rest of it though.

Pics will follow...

I bet you forget one thing...

EMI inteferance...

There is a reason why you don't see any manufacturer producing PSU out of acrylic/plastic...
However you can counter this if your mobo support "Spread Spectrum". You can set it to enable.

But the downside is, you will not be able to overclock, or else your cpu might just lock down.

The next step: Cutting the back of the case to fit the backpanel connectors.

The advantage of the DFI LanParty NF4 SLi-D board is that all of the frequently used connectors are concentrated in one position so I won't have to cut that much of the back of the case. Of course, if I change mobos, I might have to get the dremel out again. For now however, this is how it looks with the CoolerMaster Aquagate Mini in position. I've pencilled out where I will be cutting...

Three problems with this:

1. It's a lot of work
2. The G5 only has two USB ports. The DFI board has six. I need all six.
3. It's a lot of work

The way to do this is to use a jigsaw with a metal cutting blade. Use it at the minimum speed in order to avoid melting the acrylic (you MUST have a variable speed jig saw - I use the Bosch one). Advancing at just the right speed is critical. Too fast and the cut tends to run off the chosen line. Too slow and the acrylic will buck and shatter. Experience is needed. Cut some spare pieces for practice first.

aiks... mind to mention what model are those?

Hey, thanks guys...
You really are TOO kind....
A few problems though... While the RAM has sufficient clearance, I'm a little concerned that it gets too little airflow being stuck behind the PSU. The expert board will solve this due to the vertical placement of the RAM but... no expert board!

Am considering re-doing the PSU. Perhaps a vertical placement. Unfortunately that would mean re-doing the middle shelf too.... Hmmmm.

Well I certainly don't have UMS.....

But I am interested in Crossfire/X1800 mastercards.... Will have to wait for the user opinions on the setups though.

In any case I'm at present swamped down with work. Modding will continue after christmas though! Ho! Ho! Ho!

come to think of it, i just noticed this long-gone thread. so, mc, u bz flying or still waiting for the xfire? why not settle for just 7950GX?
