1) Possibly- you need to find out what standard the current board uses (ATX, micro-ATX, BTX etc...) and get a motherboard that uses the same standard. Looks like it should take a microi-ATX voard: »www.ehow.com/info_12224122_atx-m···ase.html

The Dimension 2350 comes with a custom-made motherboard but the case will fit any motherboard of the microATX form factor.
2) I believe most Dells now use standard PSU's - should be easy to take out and check out the size fro the replacement. Other question is - why are you looking to replace the PSU? -- Brian

That Dell is very, very old and I can think of several issues you might encounter...
The front panel connector is most likely proprietary to Dell, meaning you won't be able to power on a standard motherboard. You will also not be able to use the front panel USB and audio jacks.
The PSU is likely a low wattage 20-pin model without any SATA connectors and a single 4-pin lead for the power plug near the CPU. A new motherboard will want the full 24 pins and perhaps 8 pins for the CPU.
The back plate for many Dells is not removable. You would not be able to physically put any other board in there unless all the ports line up exactly... which is very unlikely. -- My Site
I remember back when I had windows me that I could "create" an install disk from the files found in the windows folder.
I don't think so but I'm not 100% sure. I've always preferred to either clone an existing installation (when moving to a different hard drive) or use a full install CD (when wanting to start fresh with a new installation).
You can use any OEM install CD as long as the version (home or pro) matches what the sticker says on your Dell. If it's a Dell disc, you won't need to enter the key (because of preactivation). If it's not a Dell disc, you will need to use the key from the sticker. -- My Site
