I'm in the process of upgrading the case for a Dimension 4100 due to the original case being damaged. However, when I went to connect the new case's power button, led's etc. to the motherboard I found that Dell in their wisdom have neglected to mark the motherboard with what goes where.
Anybody have any idea about what terminals should be connected to what(power button, power led, hdd led etc.)?
I upgraded a friends pc and had the same issue but i solved it very simply see go out and buy a new case but before you do look at the floor model look at the connectors now most cases come with a atx universal plug it's something new i noticed and i just plugged in the plug now depending on the style you might have to reposition ( key it to the terminals) the plug to get the proper sequence but rest assure it is not that difficult did it to a friends dell and it works perfect no problems what so ever give it a try

Re: Case upgrade for Dell Dimension 4100
The easiest thing to do it is look at your motherboard and make a note of the manufacturer and model/version number, as Dell don't make their own boards.
Go to the manufacturers web site and search for the manual probably in PDF format and download it and look for the relevent power button connections.

If you do not see any activity and no beeps then the memory module could either be not seated right or was damaged by static. Or you could have knocked something loose (nah that never happens ;-])
To boot and generate a beep code the motherboard needs to see the first 64k of ram. So you can be sure that the problem or part of it will be the #1 memory module. So take it out and reseat it, and then try again. If nothing then swap it's position with the other module and see if that works.
Look around the case and then reseat any connectors. You may need to pull them off and then push them back on to be sure. The heat cycles from the boards running can cause them to work loose and then they just need a bump or a brush to disconnect. On some cases you can do the same just by picking it up by the corners. The case twists and pop.
If nothing is out and it still won;t work your other option is to start swapping parts into the other case to verify they are working.
The Dimension 5150 has a BTX case, which is nearly impossible to upgrade. The motherboard is NOT interchangeable (with a few exceptions, but none of which are true upgrades).
If you have a PCI Express slot, you can upgrade the video card but do not get a card that requires an additional power cable directly from the power supply. This is because the stock power supply is very weak and doesn't have outputs for additional cards. If the card requires no additional power, you should be fine.
You can upgrade your processor with the P4 [Prescott] 5xx or 6xx Series Processors with
HT. The 5150 does not support core 2 duo processors. Depending on what you currently have, this may or may not be worthwhile. Also note that higher power processors run at higher temps, which sometimes causes a noticeable increase in fan noise.
The hard drive is easily upgradeable. Just buy any standard sized SATA hard drive. Your computer case supports two drives, so you could keep your current drive and just add a second drive. Remember to buy a SATA cable with the new drive because new drives usually don't come with them.
Overall, if you're looking to get outstanding performance, get a new computer. BTX computers are not gaming computers. You'll end up dumping money into this thing just to get a lousy increase in performance.
if the sci36-r13 is the stock mobo that came with that pc it isnt worth upgrading pentium 4's use the LGA-775 socket this is compatible with all pentiums and core 2's (not includeing core i7), so you could put in a core 2 quad if you wanted to but it would not make much difference to performance because your motherboard would not be able to handle some of the fetures your ram would also reduce preformance
if you wanted to upgrade that computer you would have to replace everything but maybe the case
You can do this with case modification as well as a new psu as Dell used proprietary mb's, psu's & cases on this model Dimension. To tell you the truth it would probably be cheaper and easier to pick up a core2duo or quad barebones kit than trying to modify the Deimension. Just my opinion. Remember Dell psu's are not wired the same as industry standard and their motherboartds in these older units are not top quality. Hope this helps you out.
Upgrading RAM will not affect your files. Just make sure you upgrade with compatible RAM & that you install it in pairs. So if you want 2 GB then you would want to be 2 x 1 GB RAM chips. Hope this helps & please remember to rate my answer. Thanks.
Well the two would not be compatible cause one is a P3 and the next is a P4 two completely different socket types so it wouldn't work but what u can do is buy a new motherboard if u want to upgrade to a P4...thats the only thing that is recommended from such a devices cause an upgrade wouldn't be possible to do .
