Be careful what you ask for!
For the enormous box that it was in, the cMP was rather limited. Too much space was designed for cooling the nuclear fires of the PowerPC CPUs, and everything else was compromised.
Ask for a better tower, not "return" of the old tower.
For example, the MP5,1's PCIe support is:
- PCIe 2.0 x16 (used by GPU)
- PCIe 2.0 x16
- PCIe 2.0 x4 (bandwidth for x4 slots shared)
- PCIe 2.0 x4
A current Dell T7910 has:
- PCIe 3.0 x4 (x16 mechanical)
- PCIe 3.0 x16
- PCIe 2.0 x4 (x16 mechanical)
- PCIe 3.0 x16
- PCI 32-bit
- PCIe 3.0 x16 (only active with dual processors)
- PCIe 3.0 x16 (only active with dual processors)
The Dell also has:
- 16 DIMM slots for up to 512 GiB RAM (256 GiB with one processor)
- Dual optical bays
- One 5.25" full size, SATA 3
- One slimline (laptop) SATA 3
- 8 internal drives
- NVMe SSD drives
