Depending on it's size, it would likely have either an ATX or microATX motherboard.
The case, motherboard, and power supply must all be the same form factor. Obviously the motherboard and the case would have to be the same or the motherboard would never fit in the case. Then the power supply must not only fit in the case, but have the same connectors as the motherboard. Otherwise it won't work.
No. There is no possible upgrade for a computer with a 120 MHz Pentium to an 800 MHz processor. You couldn't even replace the motherboard, as the case would not support newer motherboards (AT/Baby AT vs. ATX/microATX)
ATX and MicroATX (aka uATX) are the two most common but if you look for a third that you will frequently run across, it would be mini-ITX for the small-form-factor style of machines. I don't sell many of the mini-ITX designs through my store as most people who buy from me tend to prefer the larger, more flexible build designs. It all depends on what you require, however.
The Mini ITX motherboard is only used within one computer system. It is used for small form factor or SFF computer systems. It enables an infinite development amount of SFF computer systems.

I would recommend googling the the number on the old motherboard.
The Dell OptiPlex GX150 motherboard would not support anything remotely modern in the way of RAM or a CPU. A higher capacity IDE drive may be possible, but because of the age of the system, the BIOS likely will not allow more than 127 GB of any drive to be usable. Similarly, a newer AGP card may be possible, but the performance would be limited due to the slower speed of the AGP bus on the motherboard. Not to mention that, if you have one of the slimline models, you would have to find an appropriately sized card. The motherboard would be nearly impossible as well. The Optiplex models use a proprietary form factor, not a standard one like ATX or microATX. So upgrades can only be purchased from Dell.
depends on the motherboard, but average would be 4gb.
A abit LG-957 motherboard would be best for a graphic designer.
you would want to change your motherboard basically why i want to..is that you bought a PCI-express card but your motherboard doesnt support that.or you want a faster processor that your old motherboard doesnt support. hope this info helps.
you would have to consider if there are other hardware upgrades that would have to be done as a result for instance if you have a motherboard with ddr ram but the new motherboard has ddr2 you would have to by new ram same with power supply and even hard drives
