SuperMac C500

That's either a Umax SuperMac C500 or a J710. Here's an excellent site detailing all of SuperMac's products.

The C500s are one of the more common clones but they are still sought after. I'd expect to get between at least $150 for it but $1,000 is high. That sort of price is reserved for the ultra-rare clones like the Daystar Genesis MP or SuperMac S900DP/S910.

If it's a J710 it's a much more unusual machine but they are not in crazily high demand. I think you'd see a sale price of at least $250 for a J710 but it could go a lot higher if it has one of the unobtainium G3 upgrades.

I bought one of those for my grandfather some time after the end of the clone era. I think it came from Small Dog.

Ha. Yeah they weren't terribly pretty, were they? Akia in Japan made a rebadged version of this with a slightly different front panel and a stand to orient it on its side instead of as a desktop.
Anyway UMAX were one of the more interesting clone builders in that these are Alchemy-based systems but they use an entirely custom logic board (Apple's Alchemy systems were the drawer-style logic boards for the 54/6400s) whereas lower-tier cloners just used a variation of the Tanzania/II architecture (which were mostly just rebadged StarMaxes). I think UMAX and PowerComputing are the only ones who built custom Alchemy systems (and UMAX would sublicense these designs to others such as Akia).

I doubt I'd pay more than $100 for it unless it was one of the top-end models with the fast L2 cache on the processor card, or one of the elusive Akia or Tatung or other off-brand cloner's version of it. I think I paid something around $100 for the UMAX Apus 2000 (which is the same thing only sold outside of the States) that I bought about two years ago.

Anyone have any idea if the case used in the SuperMac c500 series was based on a common PC version or if it was custom to Umax? Perhaps Akia licenses their tower version (MicroBook Power) from Max?

These cases do look much the same as popular generic "book PCs" of the era, but you'd assume are completely custom internals.
