proccessor is too weak, ram can probaby be sweapped out but an i3 or higer is best for rigs now due to algos like mtp
The processor does not matter as the GPUS are the main reason for this rig, you could probably still mine on the CPU, one extra hash is one extra hash, right?
It only has to do one job, is not a media centre or gaming PC... Nice looking unit anyway, looks well made too. Would be good if there were a choice of PSUs if you did not want to utilize or need all that power.
You didn't read what Marvell2 wrote. Yes, this CPU is too weak for algos like mtp (and its very likely soon-to-come offsprings).
The box does look good indeed, but nowadays if you want something future proof, you'll need to get more than a Celery and at least 8GB of ram.
The memory is upgradable, so making this rig future proof is not a problem. I would say the only potential limiting factor is the PSU, but then again that can also be swapped out.
