I'm putting together computer specs for a new small core lab, and I am between the HP Z840 and the Dell Precision Tower 7000 series. Does anyone have a preference for one versus the other when it comes to analysis for RNA-seq, genome, and methylation-seq analysis (no de novo)? I will be the only user of this workstation, and I will have access to additional server storage space. Current project load is 6 RNA-seq projects and 1 methylation-seq project.
I would really appreciate feedback on the following build from members that routinely run human/mouse RNA-seq analysis:
Dell Precision Tower 7810
-Intel® Xeon® Processor E5-2660 v4 (14C, 2.0GHz, 3.2GHz Turbo, 2400MHz, 35MB, 105W)...do I need more cores?
-Red Hat Enterprise Linux WS v7.2...is Ubuntu preferable?
-NVIDIA® Quadro® K620 2GB (DP, DL-DVI-I) (1 DP to SL-DVI adapter)...is this overkill or should I stick with the standard AMD GPU?
-128GB (4x32GB) 2400MHz DDR4 RDIMM ECC...can I get by with 64GB?
-Internal Hard Drive Configuration: C2 SATA / SSD 3.5 Inch, 3 Hard Drives (Integrated Controller)
-Hard Drive: 4TB 3.5" Serial-ATA (5,400 RPM) Hard Drive
-2nd Hard Drive: 2TB 3.5" Serial-ATA (7,200 RPM) Hard Drive
-3rd Hard Drive: 2TB 3.5" Serial-ATA (7,200 RPM) Hard Drive
