Specs can be found online but this bundle has an 8GB DDR3L DIMM installed and it has a soldered on J2900 Quad Core Pentium CPU that is passively cooled, PCI-e I believe is an electronically 8x slot but full 16x width physically so can take a GPU (I personally tested with a SAS HBA & 10Gb NIC's and used the onboard GPU with great results).
