I think this one will do but I hope everything will match.
I want to replace my TH7ii with a Intel D865PESO Intel 865PE Socket
478 uATX MB w/Snd & LAN
Will I be able to use my current powersupply, memory, AGP graphics
card and cpu? I don't use RAID anymore.
I am tole that a uATX will fit in a standard case, but I would like
conformation on that too.
Power supply - yes. If you are using the same processor chip, then the
+12V drain will be the same on the new board. The 3.3V will use maybe
14A (the 3.3V might be used to power the RAM and the chipset). Your old
board will be slightly different in its powering method, and loading on
3.3V and 5V, but this is probably not an issue.
The TH7ii has 20 pin main power, 2x2 ATX12V power for the processor, and
room for the 1x6 Aux power connector. You won't need the Aux on the Intel
board.
Memory on the TH7ii is RAMBUS RIMMs. Memory on the Intel board is unbuffered
DDR. You'll need different memory. Memory modules up to 1GB each can probably
be used.
For AGP, the TH7ii runs AGP 1X/2X/4X. The latter requires an AGP VIO of
1.5V. The new motherboard would support up to AGP 8X. One thing the new
motherboard cannot do, is run with an AGP card that is 3.3V only (those
cards are pretty old). For more info on mixing and matching, you can read
this article. If you'd said what your AGP card was, I could have looked
it up in here. It is not hard to figure out, using this article.

The TH7ii CPU socket is S478. So is the D865PESO. There is a list here
of what processors are supported.

So memory looks like the first issue. More details about your current
AGP card and which exact CPU you are using, would help narrow down the
rest of it.
Full sized ATX is 12" x 9.6". MicroATX is 9.6" x 9.6". The two formats
have mounting holes in common. Note that at least some current brands of
motherboards, cheat a bit on dimensions. The height dimension (the first
of the two numbers) will likely be maintained. The second number, the
width, is variable. This annoys some people, and with good reason. For
example, if you buy a narrow motherboard, one which is 7.4" wide instead
of the full 9.6", the mounting holes are missing along the edge. That means
that edge of the motherboard is unsupported. If you have to push on the
motherboard, in that area, you could easily bend it, which is not really
that good for the board. So, ideally, when checking the dimensions of the
board, you'd like it to be close enough to the standard dimensions, so that
the standoffs underneath the motherboard, leave it well supported.
