The 4000 would be variable depending in what, if any, drives were installed. I have a set of tested Quantum 30 GB drives and a set of tested Seagate 120 GB drives that could be installed. It has OS 4.0.860 installed and comes with a CDR Backup of the various SNAP OS and utilities. It has 128 MB of memory (I found that 128 MB was more efficient than 256 MB unless you were using a lot of JVM applications), but 256 MB can be installed. And, it already has a MOD power supply installed. It all has been tested top to bottom and runs like a swiss watch.
I have not put it on eBay yet because I have been a bit busy, plus a friend of mine has his 4000 up on eBay ($300) and I did not want to cause competition for him. But, if someone here does not grab it from me soon, it will go on eBay. As configured, no drives, 128 MB, 4.0.860 OS + CDR, and MOD power supply, I would have to say around $200 (I might negotiate a little if someone is serious). Yes, you can get them for $100 to $125, but by the time you upgrade the memory, maybe replace fans, a MOD power supply for larger drives, and upgrade the OS, you will have that much at least invested. AND, you are taking the eBay risk and don't really know what you are getting (as you already found out).
The MOD power supplies, I get $75 for them (I only have 1 left). I charge that much for them because it takes me 6 to 8 hours to make one, and then several hours to test it out with larger drives to make sure all is well. It seems simple, but it is time consuming to do it right and to cut out and drill the mounting plate to mount in the 4000. Not to mention, other replacements are $129 and up. All in all, I wasn't doing these for the money (hell no), I was doing them to help people out, but the power supply itself and my time is worth something also.

At one point, I did make up a step by step document on doing these. However, given that if a person screws up, they can fry their 4000, not to mention themselves, I have been leary about giving it out. I have to be concerned with anyone getting hurt or ruining their equipment (not to mention the legalities since I am a technician).
It is not that hard of a mod, but there are a few issues to consider. Heat is a big one. More power means more heat, and keep in mind the 4000 only has a CPU fan and one fan at the rear of the chassis. Next is the power controller. Just because you could put in and maybe cool a power supply with 15 amps on the 12v rail does NOT mean the power controller can handle that much power. Then there is the little matter of mounting the power supply into the chassis. Does it match the screw mounts of the OEM power supply (I doubt it seriously)? And if not, how you going to mount it? If you figure out how to mount it, will it clear the drive tray and chassis? All of these considerations (and few more), and you haven't even heated up the soldering iron yet. Then there is the power supply itself. An ATX is an ATX (or AT) right? Wrong. You can run into all kind of little variations. Little things like temp monitors for smart fans that if disconnected, the power supply stops working, for one example. Each power supply can have it's own little differences you have to be aware of.
I have helped a few other people make their own, but it was not uncommon for them to have mounting problems and/or problems getting it working sometimes. As I said, it is not that hard of mod. But it is time consuming, and in general, a pain in the arse. Due to all of the above, and more important, my genuine concern for people and their equipment, I will not give the instructions out to anyone who cannot convince me they are qualified to do the mod. I hope that answers your question.
