spacers (standoffs) between the mobo and case are critical, at no time can the traces on the bottom side of the mobo come in contact with the case.
Modern cpu's and mother boards require more than a 250w psu

If so, then you're right, you can't put spacers in them otherwise the board is elevated too much to align with the rest of the case (PCI cards, rear panel etc).
However, to start with, I don't trust that design personally & secondly, each one of the raised mountings must align precisely with a motherboard screw hole, otherwise as Doby said, it will short the board out.
I agree with Doby about the psu as well, you want at least a 350W psu, preferably higher.
I suggest you try another psu but also remove the board from that case & lay it on a pile of paper or card instead, and test it that way.

if the socket is 478 it should work with all 478 processors right? i'm using a celeron not a pentium 4 its still a 478 and installed perfectly and I think it should work
Yes but you have to check the mobo manufactuers website to see if the board/bios supports a celeron, a Abit discontinued product most likely don't because the celeron is relativly new so this you must check out it could be the problem.
also I think the case is alright because the mobo that used to be in there never shorted and the fan IS turning on and staying on so I doubt thats the prob
Yes but this is a different mobo and will line up different, without seeing this case and mobo it is impossible to tell if this is the problem
If you cannot use standoffs for whatever reason I strongly recommend not using this case, do as Samm suggest and lay the board on a piece of cardboard to test.

In answer to your question, Chumara, you're right, there are no other jumpers on the mobo, so check the bios settings as well. (more on that in a minute)
A few things occur to me that may or may not be causing a problem :
1. I noticed you have an OEM cpu. Are you certain that the heatsink/fan is of an adequate rating for your chip? Also, have you used a a good quality thermal paste or pad? nb, if you remove the heatsink at any point, you must clean it & reapply thermal paste.
2.I've checked your mobo manual and cannot find any mention of Celerons being supported. That doesn't mean they're not but you may want to confirm this for sure. It may simply require a bios update in order to have full celeron support.
3. Check you have the 4 pin CPU ATX connector plugged in.
4. Clear the CMOS (leave jumper on pins 2-3 for 10 secs then put back on pins 1-2)
5. If you can get the screen to come up, then in bios, make sure the CPU FSB is set to 133MHz
6. Like Doby said, if you do get the system functioning outside of the case, then I would recommend a new case. Even though the screw holes all line up with the bumps, the bumps are flattened out on top & often have a fairly broad diameter (compared to a spacer). If the boards circuitry runs close to any of the screwholes, this could be enough to short the board on the case.
NB when the board is out of case, and on pile of paper or card, (with no drives etc connected), when you plug the live power cord into the back of the psu you may find this alone causes the psu to power up.
If it doesn't, you need to start it manually. (This only applies if the soft power switch on front of case doesn't reach the mobo) :
Locate pins 6 & 8 on the PANEL1 header (bottom right corner of mobo). Make sure the PSU is plugged in & turned on. Then using a flat bladed screwdriver, just briefly bridge pins 6+8 with the screwdriver.
If you have any questions regarding this procedure, please ask!
