I have a SC750A chassis, the older one that wasn't made for Pentium 4 motherboards. Do you have a removable tray I could order to allow me to install a Pentium 4 motherboard in this case? I love this case and don't wish to use another.
The SC750A and newer chassis are of different design so there is no way to place a replacement motherboard tray in the chassis. Your chassis is good as long as you have the correct mounting holes so the motherboard will fit in without issue. The only change you will have to make is replacing the power supply with a Pentium 4 class power supply.
