It may be too extreme for you but this page shows what I did to a PC70.

I did try a chevette heater core up at the top under a 120mm blow hole in an aluminum shroud/holder attached to the 120mm fan, but didn't like the results. Plenty of room up there for the 6" x 6" core rather than the smaller, expensive BIX. I had soldered brass bungs for 1/8" pipe plugs on the heater core tanks opposite the inlet/outlet. I would slide the core out slightly and remove both plugs for the initial fill and bleed, removed just the suction side to top it off. Didn't need a t or fill line like that.

I removed my hard drive carriage altogether and relocated the case speaker. 4 rivets can put it back in, but it depends on how many drives you want to install. I only needed two upper bays for two 18GB SCSI drives.

You can mount the pump off of or in the lowest upper drive bay, but it caused too much vibration in the case, even with rubber mounts. I had to remove the case top cover and put a layer of tape between the two upper case supports and top cover to keep them from vibrating together with the pump in the upper drive bays. Harmonics are great, they try to escape at the most unsecured places. It's only 4 rivets that hold the top cover on anyway, and 8-32 screws can be installed to put it back on rather than rerivet it.

There are other PC70/71 cases in the Cool Cases forum here that can give you additional ideas.
