Remember what a stock G68 looks like?

The fan is still fitted in the above picture, but its obviously under the linear PSU. The big smoothing cap is usually mounted in a bracket on the base of the PSU, which is at the top, as seen above. I just moved the mounting bracket 90 deg to the inside of the side panel on the left. You can just see it peeking through on the left, between the PSU and the controller motherboard. That leaves space for the fan to fit between the base of the PSU and the cap. There's not enought height to lift the PSU up clear of the fan, otherwise (tried that at the weekend).

The alternative would be to rotate the PSU 180 deg about the vertical axis so the base of the PSU faces the G68 motherboard. That would be feasible if I removed the mobo support brackets, and it looks like it would give better shielding of the PSU from the electronics. Here's something I tried this evening in a similar configuration.



This is a generic 75W PSU in that orientation. It goes in, but its perilously close to the display board, and I wouldn't have any confidence in that. I'd much rather remove the mobo supports altogether. That doesn't seem to be much of a problem, as the card brackets support the mobo at the top, and this G68 has small metal brackets that secure it at the bottom, so it wouldn't be going anywhere (and you'd probably suppport the mobo when fitting the cards anyway). I'm not sure if other controllers have those brackets - my C61R doesn't for soem reason.

Of course, I could cut a hole and fit the fan in compartment made vacant by the video cards that aren't fitted to the G68J, but what I keep coming back to is a cheap, simple, standard, robust modification. I'm now leaning towards the big HDBB-105W as the ideal solution for all variants of the G68 - what do you think?
