Hello!
Long story short: I've found a deal I like on E5-2650L v3 1.8-2.5GHz. Are there any serious pitfalls I missed?
I'm finally building a new rig. A first one since 2003 (except for one latop I bough 1,5 years ago but that was not a build ;) ).
Planned setup:
Chassis: For now: a DIY open case based on a codegen 6013 "shucked" motherboard tray. In future - some real chassis. Additionally some HDD enclosures or something (not sure which ones, initially some Codegen chassis leftovers ;-) Later - some enclosures with fans or sth. I've seen plenty of types in our forums :) )...
HSF: Thermalright AXP-100RH and Narrow ILM adapter Or some HSF more capable if this one doesn't do the trick...
Motherboard: In future X10SRM-T/-TF if the HSF above cancan't cool the CPU enough (but temporarily: X10DRL-i with only one CPU socket populated - already on its way). I can test the HSF with the uATX one for a few days soon to learn if the HSF does its job.
RAM: 1xCrucial CT32G4LFD4266 32GB LRDIMM (from Crucial X10SRM-T/-TF compatibility lists) or the 64GB version if can't use X10SRM (the 64GB version is not in Crucial's X10SRM-T/-TF compatibility list but is in X10DRL's). If the AXP-100RH HSF doesn't do the trick then I can't use X10SRM and will stick to the X10DRL for longer...
PSU: Corsair RM850i (already bought - overkill but at least future proof and I'm in love with it ;-) )
HDDs: Initially 2x6TB NAS HDDs mirror :) (already bought and burnt in)
Boot pool: to be done, I guess initially a single Kingston A400 SSD 240GB which I already have, later I think I'll "downgrade" it to a 120GB one
UPS: to be bought later
Backups: not sure, still: initially probably HDDs rotated off-site. I have 3-4 more 6TB HDDs already. Thus I'll probably buy some low profile 12V-enabled eSATA bracket (this one IIRC), more HDD enclosures and some eSATA 12V cables
Disclaimer - the hyperlinks above are for information purpose - most of the things I'm byuing in local store except for the Narrow ILM adapter so far
CPU's pitfalls I'm already aware of:
I've been so excited writing this then I initially tried to use < and > to create spoiler tags ;-) Hopefully few errors left in this post.
Any pitfalls regarding the CPU then? Is the SMB performance going to be very poor (1Gbps-wise) or just sub-optimal? ("e5-2650L v3 SMB" google query was not helpful to me :( ) Or any other pitfalls I missed?

CPU's pitfalls I'm already aware of:
- the E5-2650L v3 basic freq. is less than 2GHz which may result in not optimal SMB performance (or poor performance? context: clients are 1Gbps) Turbo is 2.5GHz though
- Haswell performance will be impacted by Spectre/Meltdown/zombieland/... patches (but this could be possibly a bit minimized by using 2nd gen Xeon Scalables or E-2200 or something like this (can't recall the generation codename ;-) OTOH some benchmarks that already exist may proove me wrong, can't recall them now)
- NAS
- not too loud so Dynatron R14 Narrow ILM HSF doesn't seem to be a choice for me
- low profile - the shelf is a short-height one
- one of them not bigger than uATX (micro-ATX)
- future proof
- home media server
- home lab
- lots of native snapshots (2500) and snapshot or rsync incremental replication possibilities -> I think I need plenty of RAM to cache metadata
- possible future parts compatibility with a dual socket system.
- Dual SKT has been my dream :)
- Compatibility would let me exchange parts between rigs easily.
- Haswell CPUs have recently got significantly cheaper then before in my area thus Socket R3 choice
- 10Gbps ethernet version on X10DRL is expensive but X10SRM-TF is not very expensive comparing to X10SRM-F
and the X55x controller uses some otherwise unused PCIe lanes IIRCUpdate: I've checked the mobo's manual diagram and the former sentence is wrong. Either X550 and i350 use 8 lanes- and I have Cat.6 cables and sockets home - edit: but my pool config plan wouldn't saturate it and I can't imagine when I may need 10Gbps
- systems are more efficient when RAM modules are in pairs (pairs are strongly recommended)
- X10SRM uses narrow ILM and only few low profile HSFs support narrow ones so if the AXP-100RH doesn't work I need a square-ILM equipped motherboard
- an open case may need frequent
vacuum cleaning;) dust removal (don't know how often yet) - I may need to remove and replace the HSF every time I do something to the RAM modules
- I need the PSU attached to the motherboard tray since I want to put the rig on a shelf where access is limited - so I drilled a few additional holes and used some additional screws, nuts and some metal parts which names I don't know even in my mother language ;-) but they are widely available in metal and furniture stores
- eSATA bracket may cause some issues but it's for backups only
- backup drives taken off-site may need to be some archive-oriented drives (not NAS ones). I don't know. So far I have 6 NAS drives. If this is a pitfall then it's a one I have ignored/haven't checked.
- Corsair PSUs have some pitfall, for example described here
- LRDIMMs don't work with E5-16xx v2/v3/v4 ones so I'm limited do 26xx (or maybe 46xx - I don't care of 46xx for now ;-) ) nor with Atom C3xxx (possible future separate rig for other purposes). But at least if an RDIMM/C3xxx set didn't work together I could test RDIMMs with my X10 system so I could rule out defective RDIMM - a long shot)
- supermicro server motherboards have some weird front panel/controller LED connector which I am not familiar with (yet?)
- if I ever want to use 10Gbps ethernet I either can't use SMB for this or need a CPU upgrade (I might be a bit wrong - I've seen some thread somewhere else mentioning they were able to saturate 10Gbps using E5-2620v2 2.1-2.5GHz so I may "almost" saturate it. BTW 2650Lv3 has better single threaded passmark score than 2620v2 but I don't know if it's applicable to SMB)
Any pitfalls regarding the CPU then? Is the SMB performance going to be very poor (1Gbps-wise) or just sub-optimal? ("e5-2650L v3 SMB" google query was not helpful to me :( ) Or any other pitfalls I missed?
